PURPOSE:To obtain a joined body exhibiting excellent electrochemical charac teristics in a method for joining an electrode consisting of a mixture composed of electrode catalyst powder, ion exchange resin powder and binder to a titled film by specifying the materials and formation of the electrode and joining further the specific electrode thereto. CONSTITUTION:An org. solvent soln. of the ion exchange resin consisting essentially of a perfluorocarbon resin or the mixed solvent soln. composed of the org. solvent and water thereof is impregnated into the electrode catalyst powder and the solvent is evaporated by which the electrode catalyst powder deposited with the above-mentioned ion exchange resin is obtd. The mixture composed of such electrode catalyst powder and the fluororesin binder is press welded under heating to one or both surfaces of the ion exchange membrane consisting essentially of the perfluorocarbon resin to form the mixed electrode-electrolyte layer. The electrode consisting of the mixture composed of the electrode catalyst powder and the fluororesin binder is further joined to the mixed layer, by which the intended joined body is obtd. |
