È una pratica abbastanza comune nell'industria delle celle a combustibile utilizzare membrane PFSA rinforzate con uno spessore di 50 micron o meno per la maggior parte delle applicazioni commerciali (come gli stack di celle a combustibile PEM per l'industria automobilistica, gli autocarri pesanti, gli autobus, la mobilità elettrificata, i droni, gli UAV e così via). Questa membrana PFSA rinforzata meccanicamente ha uno spessore di ~6 micron ed è ideale per gli stack di celle a combustibile PEM che produrrebbero densità di corrente molto elevate e lunghe durate operative. Il rinforzo meccanico di questa membrana si basa sull'ePTFE microporoso che presenta regioni porose tridimensionali in cui il PFSA a conduzione ionica viene impregnato a umido con il metodo solution cast. Considerare la membrana PFSA rinforzata con ePTFE (spessore di 6 micron) per le celle a combustibile PEM amplierà l'orizzonte dei ricercatori, fornendo una strada altrettanto valida da esplorare, accanto alle membrane Nafion HP e Nafion XL e a molte altre membrane rinforzate con ePTFE che in passato erano lo standard d'oro del settore e che sono state abbandonate in seguito al cambiamento del mercato. \n\r\nIl principale vantaggio delle membrane PFSA rinforzate meccanicamente sarebbe la loro durata operativa significativamente maggiore rispetto alle membrane PFSA non rinforzate, grazie alle sollecitazioni legate al rigonfiamento che vengono assorbite dall'armatura in ePTFE.  Una delle principali limitazioni delle membrane PFSA rinforzate meccanicamente è la loro minore conduttività protonica o ionica rispetto alle membrane non rinforzate, a causa della minore quantità di materiale conduttore ionico per unità di volume o per unità di massa (l'armatura in ePTFE è abbastanza porosa, ma ha comunque una massa). Sebbene non sia una pratica comune, questo prodotto a membrana può essere utilizzato anche nei sensori elettrochimici e in altre tecnologie pertinenti che necessitano di una membrana a scambio protonico sottile e meccanicamente rinforzata per il suo funzionamento. \n\r\nLa membrana PFSA rinforzata in ePTFE (spessore 6 micron) per celle a combustibile PEM si basa sul materiale dell'acido perfluorosolfonico stabilizzato chimicamente e viene fornita nella forma acida (H+) (nota anche come forma protonica). La stabilizzazione chimica è nota anche come stabilizzazione del gruppo terminale, in cui gli atomi di carbonio che terminano le catene polimeriche di PFSA sono completamente fluorurati. Le membrane di PFSA stabilizzate chimicamente presentano un rilascio di ioni fluoruro sostanzialmente inferiore rispetto alle membrane di PFSA prodotte con resina PFSA non stabilizzata.  I gruppi funzionali (noti anche come siti di acido solfonico) di questa membrana PFSA si basano sulla lunga catena laterale della sua struttura chimica. \n\r\nLe membrane a scambio protonico sono note sul mercato anche come membrane a scambio cationico. Questa membrana PFSA funge da separatore e da elettrolita solido (senza la necessità di un acido liquido) in una varietà di celle elettrochimiche che richiedono che la membrana trasporti selettivamente protoni o altri vari cationi attraverso la giunzione della cella (o tra gli strati catalitici anodici e catodici). Il polimero è chimicamente resistente e durevole. \n\r\nSu un lato di questo prodotto è presente un film di supporto (noto anche come film di copertura o film di supporto) che è inerte ed è importante rimuovere questo film di supporto dalla superficie della membrana prima di utilizzare la membrana stessa.  Lo scopo principale del film di supporto è quello di proteggere la membrana durante la spedizione. \n\r\n\r\nContattateci all'indirizzo sales@fuelcellstore.com per ottenere le SDS e le schede tecniche (TDS).\u003c\/p\u003e","brand":"FCS","offers":[{"title":"36x36","offer_id":54631643021638,"sku":"78010001","price":0.0,"currency_code":"EUR","in_stock":true},{"title":"36x100","offer_id":54636708856134,"sku":"78010002","price":0.0,"currency_code":"EUR","in_stock":true},{"title":"36x200","offer_id":54636708888902,"sku":"78010003","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0533\/5600\/3482\/files\/ePTFE-reinforced-pfsa-membrane-for-fuel-cells-3-500x500.jpg?v=1749807819"},{"product_id":"fumapem-am40-pbi-copolymer","title":"Fumapem AM-40 -

D50-R ePTFE Reinforced Proton Exchange Membrane","description":"PFSA D50-R ePTFE Reinforced Proton Exchange Membrane (PEM) is used to separate the anode and cathode compartment of PEM fuel cell stacks that usually consume H2\/Air or H2\/O2 as the fuel\/oxidant and having the capability for delivering high current densities without compromising the safety aspect (which necessitates the use of a relatively thin membrane).\n\nIt is quite a common practice in the fuel cell industry to use thin (50 microns or less) reinforced or unreinforced PFSA membranes in order to achieve high current densities that are relevant to the commercial applications.\n\nPFSA D50-R ePTFE Reinforced Proton Exchange Membrane has a thickness of 50 microns (+\/- 2 microns for the variations in the thickness).\n\nThis material has a backing plastic on one side.\n\nConsidering D50-R broadens your horizon by providing an equally valuable avenue to explore, alongside Nafion 1035.\n\nThe mechanical reinforcement in this membrane is based on the microporous ePTFE which has 3-D porous regions where the ionically conducting PFSA is wet impregnated via solution cast method.\n\nThe major benefit of mechanically reinforced PFSA membranes would be their significantly enhanced operational lifetime compared to the unreinforced PFSA membranes due to swelling related stresses being taken up by the ePTFE reinforcement.\n\nOne of the major limitations of the mechanically reinforced PFSA membranes is their lower proton or ionic conductivity compared to unreinforced membranes because of less ionically conducting material per unit volume (while ePTFE reinforcement is quite porous, it does have a mass regardless).\n\nWhile this mechanically reinforced PFSA membrane was originally developed for vanadium redox flow battery applications and its ideal application would be vanadium redox flow batteries, though since it is manufactured in the protonic form, it can also be used for standard PEM fuel cell applications too.\n\nWhile it is not a common practice, this membrane product can also be used in PEM water electrolyzer, direct methanol fuel cells (DMFCs), direct formic acid fuel cells (DFAFC), microbial fuel cells (MFC) and other similar applications and it is always advised that the end-user to take into consideration of the thickness of the PFSA membrane for their particular application and how it may effect the performance positively or negatively.\n\nPFSA D50-R ePTFE Reinforced Proton Exchange Membrane is based on the chemically stabilized perfluorosulfonic acid material and it is shipped in the acid (H+) form (which is also known as protonic form).\n\nChemical stabilization is also known as end-group stabilization where the carbon atoms that end of the PFSA polymer chains are fully fluorinated.\n\nChemically stabilized PFSA membranes will exhibit substantially lower fluoride ion release compared to the PFSA membranes manufactured from unstabilized PFSA resin.\n\nFunctional groups (also known as sulfonic acid sites) for this PFSA membrane are based on the long side chain for its chemical structure.\n\nProton exchange membranes are also known as cation exchange membranes in the market.\n\nThis PFSA membrane performs as a separator and solid electrolyte (without the need of a liquid acid) in a variety of electrochemical cells that require the membrane to selectively transport protons or other various cations across the cell junction (or between anode and cathode catalyst layers).\n\nThe polymer is chemically resistant and durable.\n\nPlease contact us at sales@fuelcellstore.com for the SDS and technical data sheets (TDS).\n\n\u003ch3\u003eMembrane Properties\u003c\/h3\u003e\n\u003ctable border=\"1\"

e.g. 0.5 M NaCl solution at 25°C for 72 hrs exchanging several times the solution.\n\nDo not let the membrane dry out since micro-cracks may likely occur during shrinkage.\n\nIf you have any concerns about storage, chemical stability, pre-treatment or before proceeding, please feel free to contact us for further information.\n\nPlease note that a current lead time of one to two weeks is to be expected.\n\n\u003ch3\u003eMembrane Properties\u003c\/h3\u003e\n\u003ctable border=\"1\" cellpadding=\"5\"\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMembrane\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCation Exchange Membrane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThickness\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e114 -

TE80-R ePTFE Reinforced Proton Exchange Membrane","description":"PFSA TE80-R ePTFE Reinforced Proton Exchange Membrane (PEM) is designed to be used in high differential pressure or high balanced pressure PEM electrolyzers to separate the anode and cathode compartment for generating hydrogen and oxygen gases from water electrolysis reaction.\n\nThis proton exchange membrane (also known as cation exchange membrane) has a thickness of 80 microns (+\/- 5 microns for the thickness variation) and ideally suited for any PEM electrolyzer stacks that demand very high current densities (up to 4 A\/cm2) and long operational lifetimes.\n\nThe mechanical reinforcement in this membrane is based on the microporous ePTFE which has 3-D porous regions where the ionically conducting PFSA is wet impregnated via solution cast method.\n\nThis material has a backing plastic on one side.\n\nThe major benefit of mechanically reinforced PFSA membranes would be their significantly enhanced operational lifetime compared to the unreinforced PFSA membranes due to swelling related stresses being taken up by the ePTFE reinforcement.\n\nWhile one of the major limitations of the mechanically reinforced PFSA membranes is their lower proton or ionic conductivity because of using higher EW resin material (such as 1000 or 1100), PFSA TE80-R ePTFE Reinforced Proton Exchange Membrane is utilizing a much lower EW PFSA resin (~800) and hence have excellent proton conductivity.\n\nPFSA resins with lower EW values usually have higher ion exchange capacity (IEC) and higher available acid capacity (AAC) per unit weight of the resin material compared to other PFSA resins and hence the reason why PFSA TE80-R ePTFE Reinforced Proton Exchange Membrane has unparalleled ionic conductivity despite being a relatively thicker membrane.\n\nWhile this membrane was originally developed to be used in high pressure PEM electrolyzers, the following applications will also benefit greatly from the usage of this membrane: unpressurized or pressurized PEM fuel cells (H2\/Air), unpressurized or pressurized PEM fuel cells (H2\/O2), direct methanol fuel cells (DMFCs), direct formic acid fuel cells (DFAFC), microbial fuel cells (MFC), electrochemical sensors, vanadium redox flow batteries, and other similar applications.\n\nIt is always advised that the end-user to take into consideration of the thickness of the PFSA membranes they are intending to use for their particular application and how it may effect the performance positively or negatively.\n\nPFSA TE80-R ePTFE Reinforced Proton Exchange Membrane is based on the chemically stabilized perfluorosulfonic acid material and it is shipped in the acid (H+) form (which is also known as protonic form).\n\nChemical stabilization is also known as end-group stabilization where the carbon atoms that end of the PFSA polymer chains are fully fluorinated.\n\nChemically stabilized PFSA membranes will exhibit substantially lower fluoride ion release compared to the PFSA membranes manufactured from unstabilized PFSA resin.\n\nFunctional groups (also known as sulfonic acid sites) for this PFSA membrane are based on the long side chain for its chemical structure.\n\nProton exchange membranes are also known as cation exchange membranes in the market.\n\nThis PFSA membrane performs as a separator and solid electrolyte (without the need of a liquid acid) in a variety of electrochemical cells that require the membrane to selectively transport protons or other various cations across the cell junction (or between anode and cathode catalyst layers).\n\nThe polymer is chemically resistant and durable.\n\nElectrochemical performance: The polarization curve for this membrane was taken with a specialty electrochemical cell and it is provided solely for examplary purposes.\n\nIt likely that customers purchasing this membrane product may or may not be able to replicate this data as a result of the electrochemical performance being dependent not only on the CCM configuration, but also the other components such as anode and cathode diffusion layers, quality of the DI-water used, temperature and pressure value for the cell, testign hardware design and components used in the testing hardware itself, etc.\n\nPlease contact us at sales@fuelcellstore.com for the SDS and technical data sheets

ePTFE Reinforced, Pt Impregnated PFSA Membrane","description":"ePTFE Reinforced PFSA Membrane (6 microns thick, Pt impregnated) for PEM Fuel Cells is used to separate the anode and cathode compartment of PEM fuel cell stacks that usually consume H2\/Air as the fuel\/oxidant and requires achieving high current densities (which necessitates the use of a relatively thin membrane).\n\nIt is quite a common practice in the fuel cell industry to use reinforced PFSA membranes with a thickness of 50 microns or less for most of the commercial applications (such as PEM fuel cell stacks for automotive, heavy duty trucks, buses, electrified mobility, drones, UAVs, etc.).\n\nThis mechanically reinforced PFSA membrane has a thickness of ~6 microns and ideally suited for PEM fuel cell stacks that would yield very high current densities and long operational lifetimes.\n\nThe mechanical reinforcement in this membrane is based on the microporous ePTFE which has 3-D porous regions where the ionically conducting PFSA is wet impregnated via solution cast method.\n\nPlatinum impregnation to one face of the membrane significantly reduced the H2 gas crossover since platinum oparticles would function as a recombination catalyst where diffusing H2 molecules would be converted to water molecules.\n\nConsidering ePTFE Reinforced PFSA Membrane (6 microns thick, Pt impregnated) for PEM Fuel Cells will broaden researchers horizon by providing an equally valuable avenue to explore, alongside Nafion HP and Nafion XL membranes and several other ePTFE reinforced membrane that were golden standard in the industry in the past and have been discontinued as a result in the market shift.\n\nThe major benefit of mechanically reinforced PFSA membranes would be their significantly enhanced operational lifetime compared to the unreinforced PFSA membranes due to swelling related stresses being taken up by the ePTFE reinforcement.\n\nOne of the major limitations of the mechanically reinforced PFSA membranes is their lower proton or ionic conductivity compared to unreinforced membranes because of less ionically conducting material per unit volume or per unit mass (while ePTFE reinforcement is quite porous, it does have a mass regardless).\n\nWhile it is not a common practice, this membrane product can also be used in electrochemical sensors and other relevant technologies that would have a need for thin and mechanically reinforced proton exchange membrane for its operation. ePTFE Reinforced PFSA Membrane (6 microns thick, Pt impregnated) for PEM Fuel Cells is based on the chemically stabilized perfluorosulfonic acid material and it is shipped in the acid (H+) form (which is also known as protonic form).\n\nChemical stabilization is also known as end-group stabilization where the carbon atoms that end of the PFSA polymer chains are fully fluorinated.\n\nChemically stabilized PFSA membranes will exhibit substantially lower fluoride ion release compared to the PFSA membranes manufactured from unstabilized PFSA resin.\n\nFunctional groups (also known as sulfonic acid sites) for this PFSA membrane are based on the long side chain for its chemical structure.\n\nProton exchange membranes are also known as cation exchange membranes in the market.\n\nThis PFSA membrane performs as a separator and solid electrolyte (without the need of a liquid acid) in a variety of electrochemical cells that require the membrane to selectively transport protons or other various cations across the cell junction (or between anode and cathode catalyst layers).\n\nThe polymer is chemically resistant and durable.\n\nThis membrane has a cover film on one face in order to protect the membrane during shipping.\n\nPlatinum impregnation is done on the face that is away from the cover film.\n\nFor best utilization of the Pt impregnation from the membrane manufacturer, it is recommended that the Pt side is placed toward the anode of the electrolyzer cell (cathode of the fuel cell) electrochemical cell.\n\nThis Pt impregnation is actually a Pt opowder that is incorporated into the entire surface of the membrane on the side opposite the single backing.\n\nThis platinum layer is not sufficient to sustain the electrochemical reactions of the cells, it is only intended to react the minute crossover gases that occur naturally in all membranes.\n\nThis membrane is ready for use as it is shipped and requires no pretreatment steps.\n\nThere is a backing film (also known as cover film or supporting film) that is inert on one side of this product and it is important to remove this backing film from the membrane surface prior to using the membrane itself.\n\nThe main purpose of the backing film is to protect the membrane during shipping.\n\nPlease contact us at

ePTFE Reinforced, Pt Impregnated PFSA Membrane","description":"ePTFE Reinforced PFSA Membrane (9 microns thick, Pt impregnated) for PEM Fuel Cells is used to separate the anode and cathode compartment of PEM fuel cell stacks that usually consume H2\/Air as the fuel\/oxidant and requires achieving high current densities (which necessitates the use of a relatively thin membrane).\n\nIt is quite a common practice in the fuel cell industry to use reinforced PFSA membranes with a thickness of 50 microns or less for most of the commercial applications (such as PEM fuel cell stacks for automotive, heavy duty trucks, buses, electrified mobility, drones, UAVs, etc.).\n\nThis mechanically reinforced PFSA membrane has a thickness of ~9 microns and ideally suited for PEM fuel cell stacks that would yield very high current densities and long operational lifetimes.\n\nThe mechanical reinforcement in this membrane is based on the microporous ePTFE which has 3-D porous regions where the ionically conducting PFSA is wet impregnated via solution cast method.\n\nPlatinum impregnation to one face of the membrane significantly reduced the H2 gas crossover since platinum oparticles would function as a recombination catalyst where diffusing H2 molecules would be converted to water molecules.\n\nConsidering ePTFE Reinforced PFSA Membrane (9 microns thick, Pt impregnated) for PEM Fuel Cells will broaden researchers horizon by providing an equally valuable avenue to explore, alongside Nafion HP and Nafion XL membranes and several other ePTFE reinforced membrane that were golden standard in the industry in the past and have been discontinued as a result in the market shift.\n\nThe major benefit of mechanically reinforced PFSA membranes would be their significantly enhanced operational lifetime compared to the unreinforced PFSA membranes due to swelling related stresses being taken up by the ePTFE reinforcement.\n\nOne of the major limitations of the mechanically reinforced PFSA membranes is their lower proton or ionic conductivity compared to unreinforced membranes because of less ionically conducting material per unit volume or per unit mass (while ePTFE reinforcement is quite porous, it does have a mass regardless).\n\nWhile it is not a common practice, this membrane product can also be used in electrochemical sensors and other relevant technologies that would have a need for thin and mechanically reinforced proton exchange membrane for its operation. ePTFE Reinforced PFSA Membrane (9 microns thick, Pt impregnated) for PEM Fuel Cells is based on the chemically stabilized perfluorosulfonic acid material and it is shipped in the acid (H+) form (which is also known as protonic form).\n\nChemical stabilization is also known as end-group stabilization where the carbon atoms that end of the PFSA polymer chains are fully fluorinated.\n\nChemically stabilized PFSA membranes will exhibit substantially lower fluoride ion release compared to the PFSA membranes manufactured from unstabilized PFSA resin.\n\nFunctional groups (also known as sulfonic acid sites) for this PFSA membrane are based on the long side chain for its chemical structure.\n\nProton exchange membranes are also known as cation exchange membranes in the market.\n\nThis PFSA membrane performs as a separator and solid electrolyte (without the need of a liquid acid) in a variety of electrochemical cells that require the membrane to selectively transport protons or other various cations across the cell junction (or between anode and cathode catalyst layers).\n\nThe polymer is chemically resistant and durable.\n\nThis membrane has a cover film on one face in order to protect the membrane during shipping.\n\nPlatinum impregnation is done on the face that is away from the cover film.\n\nFor best utilization of the Pt impregnation from the membrane manufacturer, it is recommended that the Pt side is placed toward the anode of the electrolyzer cell (cathode of the fuel cell) electrochemical cell.\n\nThis Pt impregnation is actually a Pt opowder that is incorporated into the entire surface of the membrane on the side opposite the single backing.\n\nThis platinum layer is not sufficient to sustain the electrochemical reactions of the cells, it is only intended to react the minute crossover gases that occur naturally in all membranes.\n\nThis membrane is ready for use as it is shipped and requires no pretreatment steps.\n\nThere is a backing film (also known as cover film or supporting film) that is inert on one side of this product and it is important to remove this backing film from the membrane surface prior to using the membrane itself.\n\nThe main purpose of the backing film is to protect the membrane during shipping.\n\nPlease contact us at

ePTFE Reinforced, Pt Impregnated PFSA Membrane","description":"ePTFE Reinforced PFSA Membrane (12 microns thick, Pt impregnated) for PEM Fuel Cells is used to separate the anode and cathode compartment of PEM fuel cell stacks that usually consume H2\/Air as the fuel\/oxidant and requires achieving high current densities (which necessitates the use of a relatively thin membrane).\n\nIt is quite a common practice in the fuel cell industry to use reinforced PFSA membranes with a thickness of 50 microns or less for most of the commercial applications (such as PEM fuel cell stacks for automotive, heavy duty trucks, buses, electrified mobility, drones, UAVs, etc.).\n\nThis mechanically reinforced PFSA membrane has a thickness of ~12 microns and ideally suited for PEM fuel cell stacks that would yield very high current densities and long operational lifetimes.\n\nThe mechanical reinforcement in this membrane is based on the microporous ePTFE which has 3-D porous regions where the ionically conducting PFSA is wet impregnated via solution cast method.\n\nPlatinum impregnation to one face of the membrane significantly reduced the H2 gas crossover since platinum oparticles would function as a recombination catalyst where diffusing H2 molecules would be converted to water molecules.\n\nConsidering ePTFE Reinforced PFSA Membrane (12 microns thick, Pt impregnated) for PEM Fuel Cells will broaden researchers horizon by providing an equally valuable avenue to explore, alongside Nafion HP and Nafion XL membranes and several other ePTFE reinforced membrane that were golden standard in the industry in the past and have been discontinued as a result in the market shift.\n\nThe major benefit of mechanically reinforced PFSA membranes would be their significantly enhanced operational lifetime compared to the unreinforced PFSA membranes due to swelling related stresses being taken up by the ePTFE reinforcement.\n\nOne of the major limitations of the mechanically reinforced PFSA membranes is their lower proton or ionic conductivity compared to unreinforced membranes because of less ionically conducting material per unit volume or per unit mass (while ePTFE reinforcement is quite porous, it does have a mass regardless).\n\nWhile it is not a common practice, this membrane product can also be used in electrochemical sensors and other relevant technologies that would have a need for thin and mechanically reinforced proton exchange membrane for its operation. ePTFE Reinforced PFSA Membrane (12 microns thick, Pt impregnated) for PEM Fuel Cells is based on the chemically stabilized perfluorosulfonic acid material and it is shipped in the acid (H+) form (which is also known as protonic form).\n\nChemical stabilization is also known as end-group stabilization where the carbon atoms that end of the PFSA polymer chains are fully fluorinated.\n\nChemically stabilized PFSA membranes will exhibit substantially lower fluoride ion release compared to the PFSA membranes manufactured from unstabilized PFSA resin.\n\nFunctional groups (also known as sulfonic acid sites) for this PFSA membrane are based on the long side chain for its chemical structure.\n\nProton exchange membranes are also known as cation exchange membranes in the market.\n\nThis PFSA membrane performs as a separator and solid electrolyte (without the need of a liquid acid) in a variety of electrochemical cells that require the membrane to selectively transport protons or other various cations across the cell junction (or between anode and cathode catalyst layers).\n\nThe polymer is chemically resistant and durable.\n\nThis membrane has a cover film on one face in order to protect the membrane during shipping.\n\nPlatinum impregnation is done on the face that is away from the cover film.\n\nFor best utilization of the Pt impregnation from the membrane manufacturer, it is recommended that the Pt side is placed toward the anode of the electrolyzer cell (cathode of the fuel cell) electrochemical cell.\n\nThis Pt impregnation is actually a Pt opowder that is incorporated into the entire surface of the membrane on the side opposite the single backing.\n\nThis platinum layer is not sufficient to sustain the electrochemical reactions of the cells, it is only intended to react the minute crossover gases that occur naturally in all membranes.\n\nThis membrane is ready for use as it is shipped and requires no pretreatment steps.\n\nThere is a backing film (also known as cover film or supporting film) that is inert on one side of this product and it is important to remove this backing film from the membrane surface prior to using the membrane itself.\n\nThe main purpose of the backing film is to protect the membrane during shipping.\n\nPlease contact us at sales@fuelcellstore.com for the SDS and technical data sheets (TDS).\n\n\u003ch3\u003eMembrane Properties\u003c\/h3\u003e\n\u003ctable border=\"1\"

ePTFE Reinforced, Pt Impregnated PFSA Membrane","description":"ePTFE Reinforced PFSA Membrane (15 microns thick, Pt impregnated) for PEM Fuel Cells is used to separate the anode and cathode compartment of PEM fuel cell stacks that usually consume H2\/Air as the fuel\/oxidant and requires achieving high current densities (which necessitates the use of a relatively thin membrane).\n\nIt is quite a common practice in the fuel cell industry to use reinforced PFSA membranes with a thickness of 50 microns or less for most of the commercial applications (such as PEM fuel cell stacks for automotive, heavy duty trucks, buses, electrified mobility, drones, UAVs, etc.).\n\nThis mechanically reinforced PFSA membrane has a thickness of ~15 microns and ideally suited for PEM fuel cell stacks that would yield very high current densities and long operational lifetimes.\n\nThe mechanical reinforcement in this membrane is based on the microporous ePTFE which has 3-D porous regions where the ionically conducting PFSA is wet impregnated via solution cast method.\n\nPlatinum impregnation to one face of the membrane significantly reduced the H2 gas crossover since platinum oparticles would function as a recombination catalyst where diffusing H2 molecules would be converted to water molecules.\n\nConsidering ePTFE Reinforced PFSA Membrane (15 microns thick, Pt impregnated) for PEM Fuel Cells will broaden researchers horizon by providing an equally valuable avenue to explore, alongside Nafion HP and Nafion XL membranes and several other ePTFE reinforced membrane that were golden standard in the industry in the past and have been discontinued as a result in the market shift.\n\nThe major benefit of mechanically reinforced PFSA membranes would be their significantly enhanced operational lifetime compared to the unreinforced PFSA membranes due to swelling related stresses being taken up by the ePTFE reinforcement.\n\nOne of the major limitations of the mechanically reinforced PFSA membranes is their lower proton or ionic conductivity compared to unreinforced membranes because of less ionically conducting material per unit volume or per unit mass (while ePTFE reinforcement is quite porous, it does have a mass regardless).\n\nWhile it is not a common practice, this membrane product can also be used in electrochemical sensors and other relevant technologies that would have a need for thin and mechanically reinforced proton exchange membrane for its operation. ePTFE Reinforced PFSA Membrane (15 microns thick, Pt impregnated) for PEM Fuel Cells is based on the chemically stabilized perfluorosulfonic acid material and it is shipped in the acid (H+) form (which is also known as protonic form).\n\nChemical stabilization is also known as end-group stabilization where the carbon atoms that end of the PFSA polymer chains are fully fluorinated.\n\nChemically stabilized PFSA membranes will exhibit substantially lower fluoride ion release compared to the PFSA membranes manufactured from unstabilized PFSA resin.\n\nFunctional groups (also known as sulfonic acid sites) for this PFSA membrane are based on the long side chain for its chemical structure.\n\nProton exchange membranes are also known as cation exchange membranes in the market.\n\nThis PFSA membrane performs as a separator and solid electrolyte (without the need of a liquid acid) in a variety of electrochemical cells that require the membrane to selectively transport protons or other various cations across the cell junction (or between anode and cathode catalyst layers).\n\nThe polymer is chemically resistant and durable.\n\nThis membrane has a cover film on one face in order to protect the membrane during shipping.\n\nPlatinum impregnation is done on the face that is away from the cover film.\n\nFor best utilization of the Pt impregnation from the membrane manufacturer, it is recommended that the Pt side is placed toward the anode of the electrolyzer cell (cathode of the fuel cell) electrochemical cell.\n\nThis Pt impregnation is actually a Pt opowder that is incorporated into the entire surface of the membrane on the side opposite the single backing.\n\nThis platinum layer is not sufficient to sustain the electrochemical reactions of the cells, it is only intended to react the minute crossover gases that occur naturally in all membranes.\n\nThis membrane is ready for use as it is shipped and requires no pretreatment steps.\n\nThere is a backing film (also known as cover film or supporting film) that is inert on one side of this product and it is important to remove this backing film from the membrane surface prior to using the membrane itself.\n\nThe main purpose of the backing film is to protect the membrane during shipping.\n\nPlease contact us at sales@fuelcellstore.com for the SDS and technical data sheets (TDS).\n\n\u003ch3\u003eMembrane Properties\u003c\/h3\u003e\n\u003ctable border=\"1\"

ePTFE Reinforced, Pt Impregnated PFSA Membrane","description":"ePTFE Reinforced PFSA Membrane (50 microns thick, Pt impregnated) for PEM Electrolyzers is used to separate the anode and cathode compartment of PEM electrolyzer stacks that usually consume electricity and DI-water in order to generate hydrogen and oxygen gases and requires achieving high current densities (which necessitates the use of a relatively thin membrane, yet mechanically robust enough for PEM electrolyzer applications).\n\nPEM electrolyzer industry has recently been moving in the direction of using mechanically reinforced proton exchange membranes in order to provide very robust and reliable electrolyzer stacks.\n\nThis mechanically reinforced PFSA membrane has a thickness of ~50 microns and ideally suited for PEM electrolyzer stacks that would yield very high current densities and long operational lifetimes.\n\nThe mechanical reinforcement in this membrane is based on the microporous ePTFE which has 3-D porous regions where the ionically conducting PFSA is wet impregnated via solution cast method.\n\nPlatinum impregnation to one face of the membrane significantly reduces the gas crossover issues under pressurized (differential or balanced) since platinum oparticles would function as a recombination catalyst where diffusing H2 or O2 gas molecules would be converted to water and hence reducing the impurities in the generated gas streams.\n\nAnother major advantage of having the platinum oparticles impregnated to one face of the membrane is to improve the operational longevity compared to the other PFSA membranes as a result of reducing the gas crossover.\n\nConsidering ePTFE Reinforced PFSA Membrane (50 microns thick, Pt impregnated) for PEM Electrolyzers will broaden researchers horizon by providing an equally valuable avenue to explore, alongside Nafion N115 and Nafion N117 membranes (which are unreinforced membranes) and several other ePTFE reinforced membranes from other vendors.\n\nThe major benefit of mechanically reinforced PFSA membranes would be their significantly enhanced operational lifetime compared to the unreinforced PFSA membranes due to swelling related stresses being taken up by the ePTFE reinforcement.\n\nOne of the major limitations of the mechanically reinforced PFSA membranes is their lower proton or ionic conductivity compared to unreinforced membranes because of less ionically conducting material per unit volume or per unit mass (while ePTFE reinforcement is quite porous, it does have a mass regardless).\n\nWhile it is not a common practice, this membrane product can also be used in PEM fuel cells (especially H2\/O2 reactants consuming PEM fuel cells), electrochemical sensors and other relevant technologies that would have a need for thin and mechanically reinforced proton exchange membrane for its operation. ePTFE Reinforced PFSA Membrane (50 microns thick, Pt impregnated) for PEM Electrolyzers is based on the chemically stabilized perfluorosulfonic acid material and it is shipped in the acid (H+) form (which is also known as protonic form).\n\nChemical stabilization is also known as end-group stabilization where the carbon atoms that end of the PFSA polymer chains are fully fluorinated.\n\nChemically stabilized PFSA membranes will exhibit substantially lower fluoride ion release compared to the PFSA membranes manufactured from unstabilized PFSA resin.\n\nFunctional groups (also known as sulfonic acid sites) for this PFSA membrane are based on the long side chain for its chemical structure.\n\nProton exchange membranes are also known as cation exchange membranes in the market.\n\nThis PFSA membrane performs as a separator and solid electrolyte (without the need of a liquid acid) in a variety of electrochemical cells that require the membrane to selectively transport protons or other various cations across the cell junction (or between anode and cathode catalyst layers).\n\nThe polymer is chemically resistant and durable.\n\nThis membrane has a cover film on one face in order to protect the membrane during shipping.\n\nPlatinum impregnation is done on the face that is away from the cover film.\n\nFor best utilization of the Pt impregnation from the membrane manufacturer, it is recommended that the Pt side is placed toward the anode of the electrolyzer cell (cathode of the fuel cell) electrochemical cell.\n\nThis Pt impregnation is actually a Pt opowder that is incorporated into the entire surface of the membrane on the side opposite the single backing.\n\nThis platinum layer is not sufficient to sustain the electrochemical reactions of the cells, it is only intended to react the minute crossover gases that occur naturally in all membranes.\n\nThis membrane is ready for use as it is shipped and requires no pretreatment steps.\n\nThere is a backing film (also known as cover film or supporting film) that is inert on one side of this product and it is important to remove this backing film from the membrane surface prior to using the membrane itself.\n\nThe main purpose of the backing film is to protect the membrane during shipping.\n\nPlease contact us at

yet mechanically robust enough for PEM electrolyzer applications).\n\nPEM electrolyzer industry has recently been moving in the direction of using mechanically reinforced proton exchange membranes in order to provide very robust and reliable electrolyzer stacks.\n\nThis mechanically reinforced PFSA membrane has a thickness of ~80 microns and ideally suited for PEM electrolyzer stacks that would yield very high current densities and long operational lifetimes.\n\nThe mechanical reinforcement in this membrane is based on the microporous ePTFE which has 3-D porous regions where the ionically conducting PFSA is wet impregnated via solution cast method.\n\nConsidering ePTFE Reinforced PFSA Membrane (80 microns thick) for PEM Electrolyzers will broaden researchers horizon by providing an equally valuable avenue to explore, alongside Nafion N115 and Nafion N117 membranes (which are unreinforced membranes) and several other ePTFE reinforced membranes from other vendors.\n\nThe major benefit of mechanically reinforced PFSA membranes would be their significantly enhanced operational lifetime compared to the unreinforced PFSA membranes due to swelling related stresses being taken up by the ePTFE reinforcement.\n\nOne of the major limitations of the mechanically reinforced PFSA membranes is their lower proton or ionic conductivity compared to unreinforced membranes because of less ionically conducting material per unit volume or per unit mass (while ePTFE reinforcement is quite porous, it does have a mass regardless).\n\nWhile it is not a common practice, this membrane product can also be used in PEM fuel cells (especially H2\/O2 reactants consuming PEM fuel cells), electrochemical sensors and other relevant technologies that would have a need for thin and mechanically reinforced proton exchange membrane for its operation. ePTFE Reinforced PFSA Membrane (80 microns thick) for PEM Electrolyzers is based on the chemically stabilized perfluorosulfonic acid material and it is shipped in the acid (H+) form (which is also known as protonic form).\n\nChemical stabilization is also known as end-group stabilization where the carbon atoms that end of the PFSA polymer chains are fully fluorinated.\n\nChemically stabilized PFSA membranes will exhibit substantially lower fluoride ion release compared to the PFSA membranes manufactured from unstabilized PFSA resin.\n\nFunctional groups (also known as sulfonic acid sites) for this PFSA membrane are based on the long side chain for its chemical structure.\n\nProton exchange membranes are also known as cation exchange membranes in the market.\n\nThis PFSA membrane performs as a separator and solid electrolyte (without the need of a liquid acid) in a variety of electrochemical cells that require the membrane to selectively transport protons or other various cations across the cell junction (or between anode and cathode catalyst layers).\n\nThe polymer is chemically resistant and durable.\n\nThere is a backing film (also known as cover film or supporting film) that is inert on one side of this product and it is important to remove this backing film from the membrane surface prior to using the membrane itself.\n\nThe main purpose of the backing film is to protect the membrane during shipping.\n\nPlease contact us at sales@fuelcellstore.com for the SDS and technical data sheets
