摘要： 近年来,阴离子交换膜燃料电池的发展受到了广泛关注。开发具有碱稳定性能优异、电导率高的阴离子交换膜材料成为了研究的热点。阴离子交换膜(AEM)主要由聚合物骨架和阳离子基团组成,除了聚合物骨架结构,离子交换基团是影响膜碱稳定性和电导率的重要因素,因此,设计离子基团是提高膜性能的重要手段之一。本文综述了近年来功能基团分别为季铵、胍基、咪唑鎓盐、季鏻、金属配合物、N-螺环季铵盐、哌啶和吡咯等阳离子交换基团的AEM的研究进展,其中包括不同种类阳离子交换基团的AEM的结构,碱稳定性能和OH^-电导率,同时对于含有阳离子交换基团的AEM的结构设计进行了分析和展望。

Abstract: Anion exchange membrane fuel cells (AEMFCs) have attracted worldwide attention. To achieve high performance in AEMFCs, anion exchange membranes (AEMs) should own high ion conductivity and good alkaline stability. AEMs contain cationic groups and polymer backbone, while ionic groups play very important role in determining the overall stability and conductivity for the AEMs apart from polymer backbones. In this paper, the structure, alkaline stability and ion conductivity of AEMs with different kinds of cationic groups such as quaternary ammonium, guanidinium, imidazolium, phosphonium, metal cation, N-spirocyclic cations, piperidinium and pyrrolidinium are introduced in detail, and the development trend of the cationic groups are also discussed.

Key words: anion exchange membrane, ionic exchange group, alkaline stability, ionic conductivity
