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 setting an anode as near the membrane as possible in making the electrolysis of the alkali metal chloride aqueous solution in an electrolytic bath divided into an anode compartment and a cathode compartment by the cation exchange membrane. CONSTITUTION:The anode 8 made of a titanium porous plate covered with an anodic active material is welded to an anode compartment framework 4 through a rib, and 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., spring, 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. Also, the carboxylic group side of the exchange membrane 1, whose one side has carboxylic groups and the other side has a fluorocarbon polymer with sulfonic acid groups, is closely contacted with the cathode. The operation is preferably made at a high current density of 20A/dm<2> or more.
