ELECTRODE MATERIAL FOR WATER ELECTROLYSIS AND METHOD FOR PRODUCING THE SAME, AND ELECTRODE FOR WATER ELECTROLYSIS

摘要

PROBLEM TO BE SOLVED: To provide an electrode material for water electrolysis that can reduce the amount of use of Ir, is stable even under potential in water electrolysis, and can show sufficient catalytic activity.SOLUTION: An electrode material for water electrolysis comprises a carbon-based conductive aid, an electron conductive oxide carrier carried on the carbon-based conductive aid, and iridium oxide particles that are dispersedly carried on the electron conductive oxide carrier and has an average particle size of 10 nm or less.SELECTED DRAWING: Figure 7
