POSITIVE ELECTRODE FOR ALKALINE WATER ELECTROLYSIS

摘要

The purpose of the present invention is to provide a positive electrode for alkaline water electrolysis, capable of producing hydrogen by using water electrolysis using power having high output fluctuation, such as renewable energy, said positive electrode having high durability against output fluctuation. The positive electrode for alkaline water electrolysis comprises: a conductive base body containing nickel or a nickel-base alloy on at least the surface thereof; and a lithium-containing nickel oxide catalyst layer formed on the base body surface. The positive electrode for alkaline water electrolysis is characterized by the molar ratio (Li/Ni) between the lithium and nickel in the catalyst layer being within the range of 0.005-0.15.
