Title:
WATER ELECTROLYSIS CELL ELECTRODE, WATER ELECTROLYSIS CELL, WATER ELECTROLYSIS DEVICE, AND METHOD FOR PRODUCING WATER ELECTROLYSIS CELL ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2024/057715
Kind Code:
A1
Abstract:
The water electrolysis cell electrode 1 comprises a conductive substrate 10, a first layer 11, and a second layer 12. The conductive substrate 10 includes a transition metal. The first layer 11 is disposed on the conductive substrate 10 and includes two or more transition metals and oxygen. The second layer 12 is disposed on the first layer 11 and includes a layered double hydroxide (LDH) that has two or more transition metals. The first layer 11 is disposed between the conductive substrate 10 and the second layer 12 in the thickness direction of the first layer 11. The first layer 11 includes a first transition metal and a second transition metal, wherein the first transition metal is the same kind as the transition metal included in the conductive substrate 10, and the second transition metal is the same kind as the transition metal included in the second layer 12 and is different from the first transition metal. The concentration of the first transition metal in the first layer 11 is higher than the concentration of the first transition metal in the second layer 12.
