The durability towards anion exchange membrane fuel cells: current status and challenges

Abstract

This review explores the technical challenges associated with anion exchange membrane fuel cells (AEMFCs), focusing primarily on the durability and longevity of the membrane electrode assembly (MEA). It analyzes both irreversible performance degradation caused by component failure and reversible degradation driven by operational conditions such as water management and carbonation. Additionally, this review outlines a range of experimental and computational diagnostic techniques used to evaluate durability, while suggesting strategies including components development and operating condition optimization to improve both short-term durability and overall performance, contributing to the development of the next generation of AEMFCs for the future.
