Abstract

PURPOSE:To obtain caustic alkali with a low voltage especially, by closely contacting the gas and liquid permeable cathode composed of carbon powder carried platinum group metal and polytetrafluoroethylene on the cation exchange membrane and electrolyzing the aqueous solution of alkali chloride. CONSTITUTION:Platinum group metals (for example; Pt) or these alloys, are carried on carbon powder, such as active carbon, having a specific surface area of 200-1,300m<2>/g. Reducing method after impregnating water soluble salts of the platinum group metals on the carbon powder, is adopted for the carrying means. Next, aqueous dispersion composed of the carbon powder carried the platinum group metals and polytetrafluoroethylene, is stirred filtered and cake is formed on the filter. Then, the above cake is heated and closely contacted on cation exchange membrane. After that, electrolysis is carried out by using obtained cathode and supplying aqueous solution of alkali chloride to the side of anode room partitioned by the above membrane and normally, supplying water to the side of cathode room and caustic alkali is manufactured stably and advantageously extending over a long period.
