As the most attractive energy carrier, hydrogen production through electrochemical water splitting (EWS) is promising for resolving serious environmental problems derived from rapid consumption of fossil fuels globally. The proton exchange membrane electrolyzer (PEMWE) one EWS technologies and has achieved great advancements. To offer a timely reference progress PEMWE system, latest advancements developments technology are systematically reviewed. key components, including electrocatalysts, PEM, porous transport layer (PTL) as well bipolar plate (BPP), first introduced discussed, followed by electrode assembly cell design. highlights put on design electrocatalyst relationship each component performance PEMWE. Moreover, current challenges future perspectives development also discussed. There hope that this review can provide directions in perspectives.
