Engineering oxygen evolution anodes for practical water electrolysis: advances, challenges, and perspectives
Green hydrogen via renewable-powered electrolysis is vital for decarbonization, yet OER anode scalability remains a key limitation. A comparison of ALK, PEM, AEM, and SOEC technologies reveals challenges in dynamic integration. Lab-to-industrial translation suffers from mass/heat transfer and stability constraints. Understanding fluctuating operation–induced degradation is critical. Future advances demand co-design of materials, interfaces, and systems to bridge performance gaps and enable sustainable, large-scale deployment.
