FABRICATION METHOD OF MIXED METAL OXIDE ELECTRODE FOR ALKALINE WATER ELECTROLYSIS SYSTEM

摘要

The present invention relates to a manufacturing method of a mixed metal oxide electrode, which comprises a step of preparing an electrode substrate, a step of manufacturing a coating solution by mixing iridium (Ir) chloride, ruthenium (Ru) chloride and tantalum (Ta) chloride with organic solvent, and a step of applying and heat-treating the coating solution on the substrate; and a mixed metal oxide electrode manufactured thereby. The mixed metal oxide electrode according to the present invention can be used as an anode electrode for alkaline electrolysis helpfully by having excellent electrochemical properties due to addition of safety against electrochemical reaction and stability against alkali through tantalum (Ta) oxide, as well as having excellent catalytic function of ruthenium (Ru) oxide and iridium (Ir) oxide under an oxygen generation reacting condition in the strong alkali condition.
