Abstract:

Alkaline polymer electrolyte membrane fuel cell (APEMFC) has received much recent attention, primarily motivated by their fast dynamics and independence on expensive Pt-based electrocatalysts. As one of vital components of APEMFC, the alkaline polymer membrane directly influences their performance and cost. However, to date, no alkaline membrane has provided a satisfactory benchmark for use in APEMFC. Therefore, intensive efforts have been made to pursue desirable polymer membrane materials. In this article, the research progress over the last 3 years on state-of-the-art alkaline polymer electrolyte membranes for APEMFC is reviewed, including various synthesis strategies, structure-property relationships, water management, and ex situ and in situ stability tests. More specifically, some new metal- cation- based anion exchange membranes, such as ruthenium-complex-based and crown-ether-based anion exchange membranes, are commented on for the first time. Furthermore, future development prospects are also predicted.

Key words: Alkaline solid fuel cell, Alkaline polymer electrolyte membrane, Anion exchange membrane, Composite membrane, Non-Pt catalyst
