Title:
ANODE FOR ALKALINE WATER ELECTROLYSIS AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/080465
Kind Code:
A1
Abstract:
The present invention provides an anode for alkaline water electrolysis, said anode being not susceptible to deterioration in the electrolysis performance even in cases where a power with large output fluctuation such as renewable energy is used as a power source, while being capable of stably maintaining excellent catalytic activity for a long period of time. An anode 10 for alkaline water electrolysis, said anode 10 being provided with: a conductive base material 2, at least the surface of which is formed of nickel or a nickel-based alloy; and a catalyst layer 6 which is arranged on the surface of the conductive base material 2, while containing a nickel-containing metal oxide that has a spinel structure. With respect to this anode 10 for alkaline water electrolysis, the nickel-containing metal oxide contains nickel (Ni) and manganese (Mn), while having a Li/Ni/Mn/O atomic ratio of (0.0 to 0.8)/(0.4 to 0.6)/(1.0 to 1.8)/4.0.
