PURPOSE:To provide a cation exchange membrane for electrolysis that offers a sufficient voltage reducing effect by providing a porous layer formed of non- oxide ceramic particles on at least one surface of a membrane. CONSTITUTION:A gas and liquid permeable porous layer 2 which does not act as an electrode is formed on at least one surface of the anode or cathode of a cation exchange membrane 1 in an electrolytic cell. This layer 2 is formed by binding non-oxide ceramic particles consisting of carbide, nitride, boride or sulfide on the membrane surface by using a suitable assistant or medium. It is possible to electrolyze water, aq. soln. of acid and alkali, etc. with low voltage by using this cation exchange membrane. |
