A low cost, sandwich-structured thin film composite (TFC) anion exchange membrane for redox flow batteries, fuel cells, electrolysis, and other electrochemical reaction applications is described. The sandwich-structured TFC anion exchange membrane comprise...

Proton exchange membranes are described. The proton exchange membranes comprise a blend of a proton-conductive polymer and a free radical scavenging polymer having phenolic hydroxyl groups. The free radical scavenging polymer and the cation exchange polyme...

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...
