摘要
碱性膜燃料电池(AMFCs)因具备低成本及更快的氧还原动力学等特点备受关注。其中,作为离子传导介质和催化层黏结剂的碱性聚电解质是AMFCs中膜电极(MEA)的重要组成部分,其在高碱环境下的耐久性是保证AMFCs长期稳定运行的重要因素之一。综述了近些年针对碱性聚电解质耐久性的相关研究及其在AMFCs中的应用,分别总结了不同主链和阳离子基团对碱性聚电解质耐久性的影响机制,以期为碱性聚电解质分子结构的合理化设计提供参考。
Alkaline membrane fuel cells(AMFCs)have attracted much attention due to the low cost and faster oxygen reduction kinetics.Especially,in the membrane electrode assembly(MEA)of AMFCs,the durability of alkaline polyelectrolytes(as the ion conducting media and catalytic layer binders)in high alkaline environment is one of important factors ensuring the long-term stable operation of AMFCs.This article reviews the research on the durability of alkaline polyelectrolytes in recent years and their applications in AMFCs.The mechanisms by which different main chains and cationic groups affect the durability of alkaline polyelectrolytes are emphatically summarized.It is hoped to provide reference for the molecular structure rational design of alkaline polyelectrolytes.
