Abstract
The present invention provides a water electrolysis method comprising: supplying at least water into an electrolysis cell which includes a solid polymer electrolyte membrane, and an anode and a cathode disposed sandwiching the solid polymer electrolyte membrane therebetween; and providing a potential P between the anode and the cathode to generate oxygen from the anode, wherein an oxidation catalyst containing at least one of first transition metals is present on at least a part of a surface of the anode, and the potential P satisfies P<P<P, wherein Pindicates a lowest potential at which oxygen is generated from the anode, and Pindicates a lowest potential Pat which a quantitative index of a dissolved chemical species derived from the oxidation catalyst begins to show potential dependence.
