Abstract

PURPOSE:To curtail power cost consumed due to the lowering of electrolytic voltage by closely contacting a cathode with a cation exchange membrane and also by setting an anode as near the membrane as possible in making the alkali electrolysis in an electrolytic bath divided into an anode compartment and a cathode compartment by the cation exchange membrane. CONSTITUTION:In the electrolysis of an alkali metal chloride aqueous solution using the cation exchange membrane, the anode 8 made of a titanium expanded sheet covered with an anodic active material is welded to an anode compartement framework 4 through ribs 9. An iron supporting plate 10 for a porous chamber is welded to a cathode compartment framework 3 through ribs 11. By making use of the elasticity of an elastic laminate 12 having an elastic structure, e.g., metal netting, spring, wire mesh demister, etc., serving as the cathode, the cation exchange membrane 1 is pressed on the anode so as to closely contact the exchange membrane with the elastic laminate. The operation is preferably made at a high current density of 20A/dm<2> or more. The cation exchange membrane the carboxylic groups on its one side and also a fluorocarbon polymer with sulfonic acid groups on the other side.
