Abstract
A textured water-splitting membrane comprises an anion exchange layer abutting a cation exchange layer to form a heterogeneous water-splitting interface therebetween, and a textured surface having a pattern of texture features comprising spaced apart peaks and valleys. The membranes can also have an integral spacer on the membrane. A cartridge can be fabricated with a plurality of the membranes for use in an electrochemical cell. The electrochemical cell can be part of an electrochemical ion exchange system.
