ABSTRACT OF THE DISCLOSURE 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 per- meable 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 non-conductive material which is electrochemically inactive 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 formed by partitioning with an ion exchange membrane wherein a gas and liquid permeable porous non-electrode layer is bonded to at least one of the surfaces of said ion exchange membrane and an aqueous solution of an alkali metal chloride is fed into said anode compartment to form chlorine on said anode and to form an alkali metal hydroxide in said cathode compartment.
