Positive electrode for alkaline water electrolysis and method for producing positive electrode for alkaline water electrolysis

摘要

Provided are: a positive electrode for alkaline water electrolysis, which is obtained at low cost and is capable of achieving low overvoltage; and a method for producing a positive electrode for alkaline water electrolysis.A positive electrode for alkaline water electrolysis, which is characterized by forming, on the surface of a conductive base 1 that is formed from nickel or a nickel-based alloy, electrode catalyst layers 2, 3 that are formed from a first catalyst component comprising a nickel cobalt spinel oxide or a lanthanoid nickel cobalt perovskite oxide and a second catalyst component comprising at least one of iridium oxide and ruthenium oxide; and a method for producing this positive electrode for alkaline water electrolysis.
