Abstract Anion exchange membrane water electrolysis (AEMWE) has seen rapid advancements over the past decade due to its promising role in green hydrogen production. Ensuring long-term functionality is as crucial optimizing performance achieve commercial viability and industrial integration. However, few studies have systematically discussed degradation issues of this technology. Therefore, a thorough understanding AEMWE needed guide design, assembly, operation, maintenance device lifetime. To address gap, review overviewed heterogeneous across different material interface levels, focusing on several key components including catalysts, ionomers, membranes, gas diffusion layers. The influences these their interfaces catalytic efficiency, active site density, mass electron transfer capabilities were discussed. Moreover, impacts operation conditions, temperature, electrolyte composition, clamping pressure, stable assessed. Accordingly, current mitigation strategies resolve phenomena rigorously evaluated. By offering insights into operations, designing materials, improving assessment protocols for AEMWE, work will contribute enhancing stability large-scale
