Zero-gap salt electrolyzer for the anode, salt electrolytic bath, and salt electrolysis method using this

摘要

object of the present invention, the catalyst layer of the anode brine electrolyzer secure sufficient liquid permeability by high roughening, further enables the reduction of the electrolytic voltage and the zero-gap for brine electrolyzer the anode, the zero-gap brine electrolyzer, and to provide a sodium chloride electrolysis method using the same present invention includes a conductive substrate 21 having liquid permeability, the maximum value of the height difference of unevenness of the surface provided thereon conductive substrate 21 and a catalyst layer 22 is 55~70m zero-gap brine electrolyzer for anode and, as the anode 20, a cathode 30, zero-gap type sodium chloride electrolysis comprising an ion-exchange membrane I disposed in contact between the cathode 30 and the anode 20 bath, and to sodium chloride electrolysis method using the same
