Abstract
A cartridge for an ion exchanging electrochemical cell, the cartridge comprising at least one spiral wound, textured, bipolar ion exchange membrane having (i) an anion exchange layer abutting a cation exchange layer with continuous contact between the anion exchange layer and the cation exchange layer; and (ii) an exposed textured surface having a pattern of texture features. A method of manufacturing a cartridge for an ion exchange electrochemical cell comprises winding the textured, bipolar ion exchange membrane into a spiral wound membrane.
