Degradation Pathways in PEM Water Electrolyzers: Insights from Nafion N115 Membranes with Pt Black and Ir-Ru Oxide Catalysts

Proton exchange membrane water electrolysis (PEMWE) is a key technology for sustainable hydrogen production, yet long-term stability remains a challenge. This study evaluates degradation mechanisms in a 25 cm² catalyst-coated membrane electrolyzer cell using IrO₂/RuO₂ as anodic and Pt-based cathodic...
