N2 - Proton exchange membrane electrolyzer cells (PEMECs) with its high efficiency even at low-temperature operating conditions, have received more attention for hydrogen/oxygen generation and energy storage. Liquid/gas diffusion layers (LGDLs), which are located between the catalyst layers (CLs) and bipolar plates (BPs), play an important role in enhancing the performance of water splitting in PEMECs. They are expected to transport electrons, heat, and reactants/products simultaneously with minimum voltage, current, thermal, interfacial, and fluidic losses. In this study, a set of novel planar titanium based thin LGDLs with straight-through pores and well-tunable pore morphologies, named as TT-LGDLs, is developed by taking advantage of advanced micro/nano manufacturing methods. The TT-LGDLs with different pore shapes have been in-situ tested in a regular PEMEC and the novel TT-LGDLs have achieved a superior performance, which is only 1.639 V at 2.0 A/cm2 and 80 oC with a commercial catalyst coated membrane (CCM). This novel TT-LGDLs can be a new guide for future research and development towards high-efficiency and low-cost hydrogen energy.
