| 520 | _ | _ | |a Understanding membrane degradation under realistic conditions is critical to improve the lifetime and commercial viability of PEM electrolyzers. This study re-evaluates conventional ex-situ Fenton degradation tests, which simulate long-term radical-driven membrane damage using high concentrations of Fe²⁺ and H₂O₂. This study focuses on evaluating their relevance to in-operando degradation mechanisms and to gain an in-depth understanding of morphological and chemical degradation processes. By combining microscopic, spectroscopic, and electrochemical analyses, it is observed that morphological damage from oxygen evolution, rather than radical-induced chain scission, dominates under “Fenton-like” AST conditions. This challenges current AST design and motivates revised protocols aligned with true PEM electrolyzer operation. |
