Abstract

An electrochemical cell (101) comprises an ion exchange membrane (10) having anion and cation exchange materials. The membrane (10) can have separate anion and cation exchange layers (12, 14) that define a heterogeneous water-splitting interface therebetween. In one version, the membrane (10) has textured surface having a pattern of texture features (26) comprising spaced apart peaks (28) and valleys (30). The membranes (10) can also have an integral spacer (80) for insertion in a housing (129) of the electrochemical cell (102). The housing (129) can also have a detachable lid (96) that fits on the cartridge (100). The electrochemical cell (102) can be part of an ion controlling apparatus (120).
