Abstract
A water electrolysis apparatus includes a plurality of unit cells. A membrane electrode assembly of the unit cell includes an anode side power feeding element and a cathode side power feeding element stacked on an anode catalyst layer and a cathode catalyst layer on both surfaces of a solid polymer electrolyte membrane. A surface of the anode side power feeding element is subjected to a grinding process, and then, subjected to an etching process to form a smooth surface.
