摘要： A cation exchange membrane having gas- and liquid-permeable inactive porous layers on at least one surface is interposed between an anode and a cathode. At least one of the anode and cathode is a flexible pored electrode having a larger rigidity than that of the cation exchange membrane. The flexible extrode is deformed by an electric conductive support, so that the flexible electrode comes in close contact with the other electrode through the cation exchange membrane. An alkali hydroxide is produced with a lower potential in a diaphragm process.

摘要： An alkali metal hydroxide is produced by electrolyzing an aqueous solution of an alkali metal chloride fed into an anode compartment in a cell having an anode compartment and a cathode compartment formed by partitioning with a cation exchange membrane. A cation exchange membrane of a fluorinated polymer having carboxylic acid groups at a content of 0.9 to 2.0 meq./g. dry resin is used as said cation exchange membrane and a metal or a metal ion is incorporated in said aqueous solution of an alkali metal chloride to form a thin layer made of a metal hydroxide or oxide on the surface of said membrane in the anode compartment.

摘要： A monopolar ion exchange membrane electrolytic cell assembly comprising a plurality of unit electrolytic cells connected electritically in parallel to one another, each formed by clamping an anode compartment frame and a cathode compartment frame with an ion exchange membrane interposed therebetween, the anode and cathode compartment frames each having a feeding and discharging system for an electrolyte and a discharging system for generated gas, wherein: (a) an anode is made of a foraminous plate fixed to the anode compartment frame so that it is close to or in contact with the ion exchange membrane, and electricity is supplied to the foraminous plate via power supply rods and/or power supply ribs from a power source located outside the cell, (b) a cathode is made of flexible foraminous metal plate having good conductivity with an electric resistance at 20 DEG C of not higher than 10 mu OMEGA .cm so that the cathode itself has a current collecting function, and one peripheral end thereof is extended outward from the cell to conduct the electricity to the exterior of the cell, and, preferably, (c) the flexible foraminous cathode plate is pressed by a resilient member from the side opposite to the side facing the ion exchange membrane, whereby the flexible cathode plate is deflected so that the cathode is close to or in contact with the ion exchange membrane.
