{"product_id":"nrel-high-pressure-lte-cell-nrel-high-pressure-low-temperature-electrolysis-cell","title":"NREL High-Pressure LTE Cell - NREL High-Pressure Low-Temperature Electrolysis Cell","description":"\u003cp\u003eDeveloped by National Renewable Energy Laboratory (NREL) High-Pressure Low-Temperature Electrolysis (LTE) Cell is on open-source cell hardware designed for repeated reassembly. This work was planned and funded by the U.S. Department of Energy’s H2NEW consortium.\u003c\/p\u003e\n\u003cp\u003eoffers a 25 cm² PEM variant produced based on the technical documentation from NREL, as well as other variants developed by according to NREL guidelines. In the former, the flow field pattern is directly translated from 25 cm² PEM variant. The dissemination of these products aims to facilitate easy access to this equipment for a wide range of users. However, if you have the capability to produce the 25 cm² PEM variant on your own, we encourage you to use the open-source files. It may turn out that if you have access to your own technical resources, this will be a more cost-effective option. 3D CAD models and 2D technical drawings for variant 25 cm² PEM are available for download.\u003c\/p\u003e\n\u003cp\u003eHigh pressure LTE operation can reduce operating costs, as it is more efficient to produce electrochemically pressurized hydrogen compared to using downstream mechanical compressors. However, the cell is also compatible with ambient pressure LTE.\u003cbr\u003eThe cell can accommodate porous transport layers of varying thicknesses. To achieve this, the number of gaskets on each side of the cell can be increased, providing a larger volume for the porous transport layer.\u003cbr\u003eOne benefit of the smaller surface area variants (1 cm² and 4 cm²) is their compatibility for testing with a potentiostat and booster. In these cases, the current levels are typically within the acceptable range for most boosters. However, for larger active surfaces with current densities up to 6 A\/cm², a high-power programmable DC power supply may be required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication note\u003c\/strong\u003e\u003cbr\u003eThe documents and drawings linked below outline the design of low-temperature electrolysis hardware that is intended to meet leak testing standards as per ASME B31.1. They also provide comprehensive cell assembly instructions and a procedure for performance benchmarking. The responsibility for safe operation at both ambient and elevated pressures lies solely with the end user, and each individual cell should be assessed on a case-by-case basis. The sealing effectiveness may be influenced by factors such as machining quality, components used in cell assembly, operating conditions, and the operational history. Pressure operations should only be conducted on qualified test stands by trained operators.\u003cbr\u003e\u003cem\u003eWrubel, Jacob, Samantha Ware, Corey Schaffer, Matt Allen, Ellis Klein, Robin Rice, Chaiwat Engtrakul, and Guido Bender. 2023. \"NREL 25-cm2 High-Pressure Low-Temperature Electrolysis Cell Hardware (Open Source).\" NREL Data Catalog.
