Recent progress in the development of anion exchange membranes for electrochemical devices

Fuel cells are widely thought of as an environmental friendly energy conversion platform for the 21st century. Unlike proton-exchange membrane fuel cells (PEMFCs), alkaline polymer electrolyte fuel cells (APEFCs) that use anion exchange membranes (AEMs) as electrolytes have drawn tremendous research attention Compared with acidic fuel cells, they have enhanced oxygen reduction reaction kinetics and use non-precious metal catalysts. In the recent years, there has been extensive research toward the development of AEMs for APEFCs, redox flow batteries (RFBs), and solid alkaline water electrolyzers. This chapter summarizes selected advances in this domain.
