COMPOSITE ANION EXCHANGE MEMBRANE AND CATALYST COATED MEMBRANE FOR ELECTROCHEMICAL DEVICES

Composite anion exchange membranes are described. The composite anion exchange membranes comprise an anion exchange polymer containing a hydrogen recombination catalyst dispersed in the anion exchange polymer. The anion exchange membrane may also include a radical scavenger. The anion exchange polymer comprises a plurality of repeating units of formula (I) Catalyst coated membranes and membrane electrode assemblies made using the composite anion exchange membranes are also described.
