Open the CIPO recordAbstract From the Canadian patent
An ion exchange membrane cell comprises an anode a, cathode, an anode compartment and a cathode compartment formed by partitioning by an ion exchange membrane. A gas and liquid permeable porous non-electrode layer is bonded to at least one of surface of said ion exchange membrane. An ion exchange membrane comprises a gas and liquid permeable porous non-electrode layer made of an electrically conductive material which has a higher over-voltage than the anode or cathode which is bonded to at, least one surface of said membrane. An aqueous solution of an alkali metal chloride is electrolyzed in an electrolytic cell comprising an anode, a cathode, an anode compartment and a cathode compartment …
