Synergistic Engineering of Membrane–Electrode Interfaces via Surface Patterning in Anion Exchange Membrane Water Electrolysis

ABSTRACT The membrane–electrode interface critically governs the performance and durability of anion exchange membrane (AEM) water electrolysis, yet engineering these interfaces in pre‐formed hydrocarbon AEMs remains challenging due to their high glass‐transition temperatures and...

Plasma‐Engineered Polyethylene‐Reinforced Anion Exchange Membranes With Low Ionic Resistance and Low Hydrogen Crossover for Water Electrolysis

ABSTRACT Anion exchange membrane water electrolysis (AEMWE) enables low‐cost green hydrogen production but remains limited by the delicate balance among ionic resistance, gas crossover, and mechanical durability in hydrocarbon‐based membranes. Although reinforced composite membra...

Reconfiguration of Localized Ruthenium Surface via Incorporating Single Platinum Atoms for Favorable Hydrogen Oxidation Catalysis

ABSTRACT Despite the fact that only 2% of active sites can satisfy hydrogen oxidation reaction (HOR) activity thanks to fast kinetics, the fuel cell anode is still dependent on catalysts with large amounts of platinum (Pt). Herein, a minimal‐cost ruthenium catalyst bearing ultral...
