Advances in Anion Exchange Membrane Water Electrolysis: From Catalyst Design to System‐Level Optimization

Abstract Anion exchange membrane water electrolysis (AEMWE) represents a promising route to cost‐effective green hydrogen production by avoiding the scarce platinum‐group metals used in proton exchange membrane systems. However, AEMWE's performance and durability remain inferior to PEM counterparts, largely due to interfacial inefficiencies within the membrane electrode assembly (MEA)—the core unit governing ion transport, water management, and catalyst stability. Recent advances emphasize integrated MEA design strategies that synergize non‐precious metal catalysts, ionomer chemistry, and electrode architectures to minimize interfacial resistance and enhance mass transport. Coupled with operando characterization and computational modeling, these holistic efforts bridge material‐level innovation with system‐level performance, offering pathways to mitigate degradation and accelerate AEMWE's scalability. This review highlights the imperative of co‐designing materials, interfaces, and operational protocols to realize efficient, durable, and commercially viable AEMWE systems for large‐scale green hydrogen production.
