CATALYTIC ELECTRODE FOR WATER ELECTROLYSIS, WATER ELECTROLYSIS DEVICE, AND PRODUCTION METHOD OF CATALYTIC ELECTRODE FOR WATER ELECTROLYSIS

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive catalytic electrode for water electrolysis that can efficiently electrolyze water.SOLUTION: A catalytic electrode for water electrolysis includes a tabular metal mesh and a catalytic layer that is only formed on a contact surface contacting the solid electrolyte membrane of the metal mesh, for reducing an oxygen overvoltage in water electrolysis or efficiently creating ozone with a high oxygen overvoltage.SELECTED DRAWING: Figure 5
