Hydrogen is one of the promising energy carrier, which can be generated with high efficiency from proton exchange membrane electrolyzer cells (PEMECs). The liquid/gas diffusion layer (LGDL), which is located between the catalyst layer (CL) and bipolar plate, is expected to transport electrons, heat, and reactants/products to and from the CL with minimum losses of voltages, currents, flow and interfaces. Due to the high potential and oxidative environment in PEMECs, the conventional material of LGDL can be easily corroded, which significantly affects the performance and durability of PEMECs. Titanium has received considerable attentions as a potential material due to its high corrosion resistance, excellent electrical and mechanical properties. In this study, thin and well-tunable titanium LGDLs are developed by taking advantage of advanced manufacturing technologies and the effects of the LGDL design parameters on the cell performance are discussed. In-situ and ex-situ characterizations are conducted in this work as well.
