Description
The Fumasep cation-exchange membrane (CEM) is used to separate the anode and cathode compartment of water electrolyzers, fuel cells, or electrodialysis due to its very low resistance, high selectivity, and high stability in pH acidic and basic environment. The polymer backbone for this membrane is based on a proprietary hydrocarbon resin.
