N2 - In the proton exchange membrane electrolyzer cell (PEMEC), a liquid/gas diffusion layer (LGDL) is located between the catalyst layer (CL) and the current distributor, which also acts as the flow field. Its functions are to transport electrons, heat, and reactants or products to and from the CL with minimal voltage, current, thermal, interfacial, and fluidic losses. Due to the high ohmic potential and high oxidative environment of the anode electrode, titanium is considered to be one of the best materials of making LGDL. In this study, a set of titanium felt LGDLs are tested to investigate the different parameters affecting the performance of PEMECs. Sputter coating and thermal nitride surface treatments are introduced to titanium felt LGDLs of PEMECs and compared with untreated LGDLSs. Performance and economic factor are discussed in this paper. Titanium-based felt layers will be compared with other porous media structuresin the future.
