Title:
POSITIVE ELECTRODE FOR ZERO-GAP TYPE BRINE ELECTROLYZER, BRINE ELECTROLYZER, AND BRINE ELECTROLYZING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/069360
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a positive electrode for a zero-gap type brine electrolyzer; a zero-gap type brine electrolyzer; and a brine electrolyzing method using the same. The positive electrode is provided with a catalyst layer having a highly roughened surface, whereby the positive electrode can ensure sufficient liquid permeability and permit a lower electrolytic voltage. The present invention pertains to: a positive electrode for a zero-gap type brine electrolyzer, said positive electrode being provided with both a liquid-permeable conductive substrate (21) and a catalyst layer (22) which is provided on the conductive substrate (21) and which has a maximum height difference of surface roughness of 55 to 70μm; a zero-gap type brine electrolyzer provided with a positive electrode (20), a negative electrode (30) and an ion exchange membrane (I) which is disposed between the electrodes (20,30) in such a state that the membrane (I) is in contact with the electrodes (20,30); and a brine electrolyzing method using the same.
