Progress of Alkaline Anion Exchange Membranes

Alkaline fuel cells (AFCs),a kind of devices which can convert chemical energy into electric energy directly, have attracted considerable attention in the fields of science and industry with the advantages of high energy-conversion efficiencies and environmental protection.As the key component of AFCs,the anion exchange membranes require excellent ionic conductivity,high chemical stability,mechanical strength and low water swelling.This review reports the research progress of the anion exchange membranes,especially on the structure-alkaline stability relationships of polymer backbones and cations.
