PURPOSE:To develop the solid polymer electrolyte membrane device which is not corroded when supplied with a power by providing a porous anode and cathode on both sides of the membrane and fixing a current collecting electrode coated with a film resistant to moisture and corrosion on both electrodes. CONSTITUTION:Porous Pt plating films 2 and 3 are formed in 1-5mum thickness on both sides of the solid-polymer electrode membrane 1 having a cation- exchange function by electroless plating, for example, and the current collecting electrodes 14 and 15 consisting of an Ag paste and having 0.2mm width and about 0.2mm thickness are formed thereon at intervals of about 10mm by screen printing, etc. Polyurethane-resin coating films 16 and 17 are formed on the electrodes 14 and 15 to cover them by thermosetting. The treated solid-polymer electrolyte membrane 1a is held in a metallic mold, and a synthetic resin is injected to form a framework 18 and to cover the exposed part 1b. By this structure, a power is supplied without contact with external air, and the corrosion of the device is prevented. |
