Abstract:
A process for the production of an electrode comprising a hydrogen-storing metal body having formed on at least a part of a surface thereof a porous catalyst layer comprising a catalyst metal, which comprises contacting a first surface of the hydrogen-storing metal body with an electroless plating solution containing a cation of the catalyst metal and contacting a second surface of the hydrogen-storing metal body with an electrolytic solution, said hydrogen-storing metal body serving as a cathode and being opposed to an anode in contact with said electrolytic solution, subjecting the electrolytic solution to electrolysis to produce hydrogen on said second surface, said hydrogen being adsorbed in said hydrogen-storing metal body and moving through the hydrogen-storing metal body to reach said first surface, said hydrogen which reaches the first surface being desorbed from the hydrogen-storing metal body to produce active hydrogen, and said active hydrogen reducing the metal cation in the electroless solution so as to plate catalyst metal on said first surface.
