Stability challenge in anion exchange membrane for fuel cells

Polymeric membrane based fuel cells are becoming increasingly important in light of their high efficiency. However, the wide application of proton exchange membrane fuel cell (PEMFC) was hindered by its high cost and total dependency on Pt catalysts. The steep rising of anion exchange membrane fuel cells (AEMFCs) could be more beneficial as they have got the potentiality to settle this obstacle in a more cost effective way. Anion conducting material (especially polymeric membranes and hybrid membranes), known as an important and vital component face limitation in practical application due to its low stability under strong basic conditions. Herein, we presented the recent research findings on anion exchange membrane (AEM) stability issues and the practice in constructing alkaline stable AEMs. The stability issue in anion conductive metal organic frameworks (MOFs) was also covered.
