This review introduces alkaline anion-exchange membranes (AAEM), the alkaline equivalents to the better known proton-exchange membranes (PEM), their chemistries, and their applications in hydrogen solid alkaline fuel cells (SAFC). There has been a recent increase in understanding of AAEM behaviour in SAFCs; however, the field is still in its infancy compared to proton-exchange membranes fuel cells (PEMFCs). Current AAEMs only exhibit adequate properties for application in SAFCs at higher humidities. Thinner AAEMs perform best due to facilitated supply of reactant water to the cathode oxygen reduction sites and reduced internal resistances. Further developments in alkaline ionomers are urgently required for high performance SAFCs.
