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.

A textured water-splitting bipolar membrane comprising:
- (a) an anion exchange layer abutting a cation exchange layer to form a heterogeneous water-splitting interface therebetween;
- and
- (b) an exposed textured surface having a pattern of texture features comprising spaced apart peaks and valleys, wherein the texture features comprise a dimension of at least about 10 microns.
A cartridge for an ion exchanging electrochemical cell, the cartridge comprising:
- (a) a plurality of textured bipolar membranes abutting one another, each membrane having:
- (i)an anion exchange layer abutting a cation exchange layer to form a heterogeneous water-splitting interface therebetween;
- and
- (ii) an exposed textured surface having a pattern of texture features comprising spaced apart peaks and valleys.
A cartridge for an ion exchanging electrochemical cell, the cartridge comprising:
- a plurality of textured bipolar membranes abutting one another and spiral wrapped, each membrane having:
- (i) an anion exchange layer abutting a cation exchange layer to form a heterogeneous water-splitting interface therebetween;
- and
- (ii) an exposed textured surface having a pattern of texture features comprising spaced apart peaks and valleys.
