Abstract
An electrochemical cell 102 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 a 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. A cartridge 100 can be fabricated with a plurality of the membranes 10 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.
