Abstract

Membranes for electrochemical technologies that operate at non-extreme acidic or basic conditions are described herein. The membrane can be a bipolar membrane having an anion-exchange layer, a cation-exchange layer, and a polymer layer containing a catalyst juxtaposed between the two layers. The catalyst can improve the rate for water dissociation and water formation at low applied bias thereby decreasing the overpotential and resistance for overall ion transport, especially when unequal pH values are used between the catholyte and anolyte.
