Title:
ANODE FOR ALKALINE WATER ELECTROLYSIS AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/080466
Kind Code:
A1
Abstract:
The present invention provides an anode for alkaline water electrolysis, said anode being not susceptible to deterioration of electrolysis performance even in cases where a power with large output fluctuation such as renewable energy is used as a power source, and being capable of stably maintaining excellent catalytic activity for a long period of time. The anode 10 for alkaline water electrolysis is provided with a conductive substrate 2 in which at least a surface comprises nickel or a nickel-based alloy and a catalyst layer 6 which is arranged on the surface of the conductive substrate 2 and comprises a metal composite oxide having a quadruple perovskite oxide structure, in which the metal composite oxide contains calcium (Ca), manganese (Mn) and nickel (Ni) in which the Ca/Mn/Ni/O atomic ratio is (1.0)/(6.6-7.0)/(0.1-0.4)/12.0.
