Abstract
The present invention provides a bonded membrane-electrode assembly for electrolysis of water, which enables the generation of hydrogen capable of being used as a fuel for a fuel cell by electrolyzing water, and a water electrolyzer constructed using the bonded membrane-electrode assembly, so that hydrogen can be produced safely. The bonded membrane-electrode assembly includes a solid polymer electrolyte membrane, an oxygen electrode bonded to one of sides of the solid polymer electrolyte membrane, a hydrogen electrode bonded to the other side of the solid polymer electrolyte membrane. The oxygen electrode includes a porous sheet-shaped carbon element plated with iridium and coated with a mixture containing carbon and a resin for a solid polymer membrane. The hydrogen electrode includes a porous sheet-shaped carbon element which is coated with a mixture containing carbon and a resin for a solid polymer membrane and further coated with a mixture containing Pt (alloy) and/or Pt (alloy)-carried carbon and a resin for a solid polymer membrane.
