Title:
ALKALINE WATER ELECTROLYSIS METHOD AND ALKALINE WATER ELECTROLYSIS ANODE
Document Type and Number:
WIPO Patent Application WO/2020/184607
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrolysis technique in which electrolysis performance is unlikely to deteriorate and excellent catalytic activity is stably maintained for a long period of time even when a power source with large output fluctuations such as renewable energy is used. This purpose is realized by an alkaline water electrolysis method and an alkaline water electrolysis anode, the alkaline water electrolysis method is characterized in that an electrolytic solution in which a catalyst including a hybrid cobalt hydroxide nanosheet (Co-NS), which is a composite of a metal hydroxide and an organic substance, is dispersed, is supplied to an anode chamber and a cathode chamber, which constitute an electrolytic cell, and commonly used for electrolysis in each chamber.
