This c\u003c\/span\u003earbon paper substrate treated with 13% PTFE (polytetrafluoroethylene) is typically used as a gas diffusion layer (GDL) in various electrochemical devices, including fuel cells and electrolyzers. Its primary role in such applications is to facilitate gas diffusion while also acting as a current collector. PTFE is a hydrophobic material that is applied to carbon paper to improve its water management capabilities. The 13% PTFE content helps to make the surface more water-repellent, preventing excessive water retention in the gas diffusion layer while still allowing gases (such as hydrogen or oxygen in a fuel cell) to diffuse through.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication note\u003cbr\u003e\u003c\/strong\u003eIn a fuel cell or electrolyzer, the carbon paper treated with PTFE acts as a GDL. It provides a pathway for gases (like hydrogen or oxygen) to reach the catalyst layer while also conducting electrons to the external circuit, functioning as both a current collector and a gas diffusion medium.\u003cbr\u003ePlease note that for current collection purposes alone, carbon paper treated with PTFE might not be the optimal choice compared to traditional metal current collectors like titanium, stainless steel, or nickel. These metals are often preferred due to their superior electrical conductivity and mechanical robustness, especially in applications where direct electrical contact and durability are crucial.\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\u003cspan style=\"mso-ansi-language: EN-US;\" lang=\"EN-US\"\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003cbr\u003e\u003c\/strong\u003e\u003cspan\u003ebrand: Ballard Material Products\u003cbr\u003emodel: AvCarb P75T\u003cbr\u003ethickness: 255 \u003c\/span\u003e\u003cspan lang=\"en-SE\"\u003eµm at \u003cspan\u003e 0.7 N\/cm², and 240 µm at  5.1 N\/cm²\u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003ethrough-plane resistivity: 13.4 mOhm*cm²\u003cbr\u003esubstrate PTFE treatment: 13 wt%\u003cbr\u003emicroporous layer (MPL): None\u003cbr\u003ecutting method: die cutting\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIntrastat data\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eHS Code: 4809.90\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eCountry of Origin: Sweden\u003c\/span\u003e\u003cbr\u003eNET weight: \u0026lt;10 g\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct includes\u003c\/strong\u003e\u003cbr\u003e10 x Metal Foam Electrode\/Current Collector of selected size and material\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRelated products\u003cbr\u003e\u003c\/strong\u003eElectrochemical Cells\u003cbr\u003ePhoto-electrochemical Cells\u003cbr\u003eSpectro-electrochemical Cells\u003cbr\u003eHolders \u0026amp; Adapters\u003cbr\u003eEtch Cells\u003c\/p\u003e","brand":"redox.me","offers":[{"title":"25 mm","offer_id":56885627126086,"sku":"E-AvC_P75T-25diax1.5-10p","price":90.0,"currency_code":"EUR","in_stock":true},{"title":"20 mm","offer_id":56885627158854,"sku":"E-AvC_P75T-20diax1.5-10p","price":85.0,"currency_code":"EUR","in_stock":true},{"title":"18 mm","offer_id":56885627191622,"sku":"E-AvC_P75T-18diax1.5-10p","price":80.0,"currency_code":"EUR","in_stock":true},{"title":"16 mm","offer_id":56885627224390,"sku":"E-AvC_P75T-16diax1.5-10p","price":75.0,"currency_code":"EUR","in_stock":true},{"title":"15 mm","offer_id":56885627257158,"sku":"E-AvC_P75T-15diax1.5-10p","price":70.0,"currency_code":"EUR","in_stock":true},{"title":"14 mm","offer_id":56885627289926,"sku":"E-AvC_P75T-14diax1.5-10p","price":65.0,"currency_code":"EUR","in_stock":true},{"title":"12 mm","offer_id":56885627322694,"sku":"E-AvC_P75T-12diax1.5-10p","price":60.0,"currency_code":"EUR","in_stock":true},{"title":"11.3 mm","offer_id":56885627355462,"sku":"E-AvC_P75T-11.3diax1.5-10p","price":55.0,"currency_code":"EUR","in_stock":true},{"title":"10 mm","offer_id":56885627388230,"sku":"E-AvC_P75T-10diax1.5-10p","price":50.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0533\/5600\/3482\/files\/1_9e7801b9-4379-4e07-9351-eabdcefa4b9b.png?v=1782911670","url":"https:\/\/www.thasar.com\/it\/products\/carbon-paper-substrate-set-of-10","provider":"Thasar S.r.l.","version":"1.0","type":"link"}
