[54] AN APPARATUS AND METHOD FOR ELECTROCHEMICAL PRODUCTION OF OXIDANT RELATED COMPOUNDS
[57] Abstract: The present disclosure describes an electrochemical cell that has an electric power source, an anode, a gas diffusion cathode and a gas space in communication with the gas diffusion cathode. The gas diffusion cathode includes an ion exchange coating that faces the anode. The ion exchange coating is a polymer that also protects the gas diffusion cathode. A feed solution flows between the ion exchange coating and the anode. The gas space contains at least some oxygen gas that diffuses into the gas diffusion cathode. Within the gas diffusion cathode oxygen reacts to produce hydroxide radicals. The anion exchange coating transports the hydroxide radicals from the gas diffusion cathode to electrochemically produce oxidant-based biocides.
