An Overview of Commercial and Non‐commercial Anion Exchange Membranes

Anion exchange membrane fuel cells (AEMFCs) have received increasing attention in recent years, as they allow for the application of inexpensive anion exchange membranes (AEMs) and non-precious metal catalysts, which could greatly reduce the cost of devices. However, due to limitations of key materials such as AEMs, the development of AEMFCs is slow. Therefore, in the past few years, researchers have been committed to developing high-performance AEMs. In order to better understand the research progress and development trend of AEMs, in this chapter, first, the characteristics and existing problems of the commercial membranes (such as A201 [Japan], Fumasep ® FAA3 [Germany], AEMION™ [Canada] et al.) have been summarized. Then, in view of the problems of commercial AEMs, the content and characteristics of current research on non-commercial AEMs have been clarified by comparing commercial and non-commercial AEMs.
