Efficient electrochemical energy conversion technologies, such as fuel cells and water electrolyzers, require high current densities to lower the capital cost for large-scale commercialization but are often limited by mass transport. In this study, we demonstrated exceptional performances in proton electrolyte membrane electrolyzers (PEMWEs) creating micropatterned pore channels porous transport layer (MPC PTL) using a picosecond laser. This approach yielded an impressive performance of 1.82 V @ 2 A·cm
