Abstract Designing heterogeneous interface to enhance the kinetics for electrocatalysts is a highly efficient but challenging pathway toward hydrogen evolution reaction (HER) in water electrolysis. Herein, coupling of CeO 2 quantum dots onto porous Ru aerogel through interfacial Ru‐O‐Ce bridge proposed construct ‐Ru as superior HER electrocatalyst with ultra‐low overpotentials. In situ characterizations and theoretical calculations reveal electron distribution at boost bonding sites, faster adsorption dissociation sites kinetics. Furthermore, employed excellent cathodes both acidic alkaline electrolyzers ampere‐level current density stably operated over 500 hours. Thus, synergistic effect tunes catalytic mechanism reinforces activity, realizing generation

Abstract Proton exchange membrane water electrolysis (PEMWE) represents a promising technology for renewable hydrogen production. However, the large‐scale commercialization of PEMWE faces challenges due to need acid oxygen evolution reaction (OER) catalysts with long‐term stability and corrosion‐resistant electrode assemblies (MEA). This review thoroughly examines deactivation mechanisms acidic OER crucial factors affecting assembly instability in complex environments, including catalyst degradation, dynamic behavior at MEA triple‐phase boundary, equipment failures. Targeted solutions are proposed, improvements, optimized designs, operational strategies. Finally, highlights perspectives on strict activity/stability evaluation standards, situ/operando characteristics, practical electrolyzer optimization. These insights emphasize interrelationship between catalysts, MEAs, activity, stability, offering new guidance accelerating systems.
