Abstract

PURPOSE:To effectively take out caustic alkali from the side of cathode unit especially, by closely sticking the anode unit of gas.liquid permeating body closely stuck the anode on both side faces of electric current collecting body and cathode unit having entirely the same construction through cation exchange membrane and supplying the liquid to be electrolyzed to the side of the anode unit. CONSTITUTION:Anode unit is constructed by closely sticking the gas permeable anode 2 (for example; platinum) on both sides of the gas.liquid permeable electric current collecting body 1. On the one hand, cathode unit is constructed by closely sticking the gas.liquid permeable electric current collecting body 3. Next, the anode 2 and cathode 4 are closely stuck by the cation exchange membrane 5 and plural pairs of unit composed of cathode unit/cation exchange membrane/cathode unit, are constructed. After that, the liquid to be electrolyzed, such as alkali chloride, etc., is introduced into the part of the body 1 having the anode unit and on the one hand, water is supplied to the body 3. Then, the liquid to be electrolyzed is electrolyzed turning on direct current of +, - for each body 1, 3 and electrolyte, especially caustic alkali, is taken out from the part of the body 3.
