The effect of amide and sulphide anion functional group on the conductivity and performance of alkaline anion exchange membrane fuel cells (AAEMFCs) is reported. TMA functionalised (LDPE-co-VBC) or PVBC offered the highest conductivity with values up to 0.043 S cm~(-1). TMA functionalized electrodes showed superior cell performance in comparison to the other functional groups with a current density of 0.72 A cm~(-2) at 0.6 V and a peak power density of 478 mW cm~(-2) . The membrane exhibits good long term stability at temperatures up to 70 °C. A study of a water electrolyser with alkaline anion exchange membranes with Cu_xMn_(0.9-x)Co_(2.1)O_4 (CuMnO) catalysts gave promising performance using a quaternary OH~- ion ionomer binder based on polymethacrylate. Satisfactory stability of the membrane electrode assembly was observed from chronocoulometry.
