Abstract

PURPOSE:To reduce the electrolytic voltage and to improved the chlorine resistance and alkali resistance, by constructing the anode by a specific formula of pyrochlore type or perovskite type composite oxide. CONSTITUTION:Cation exchange membrane composed of copolymer of gas and liquid permeable fluorinated olefin monomer and polymeric fluorine monomer containing carboxylic acid radical or functional group being capable of converting into carboxylic acid radical, is prepared. Concentration of carboxylic acid per 1g said dried resin, is 0.5-2 milliequivalent. Next, composite oxide of pyrochlore type having the general formula I or perovskite type having the general formula II, is pulverized in 200-500 mesh and is pasted by adding the binder of fluorine polymer and surface active agent. And, for example, said pasted oxide is applied on aluminum foil and is heated and pressure welded on the ion exchange membrane. Here, the aluminum foil is dissolved by caustic alkali and is removed and then, porous anode is formed on said ion exchange membrane.
