PURPOSE:To increase contact area and improve adhesion by applying a mixture of a solid polymer electrolytic solution and the main component particle of a gas diffused electrode onto one surface of a reactive layer, and hot-pressing this to the solid polymer electrolytic film. CONSTITUTION:A paste in which a solid polymer electrolytic solution is mixed with the main component particle of a gas diffused electrode is applied. This is hot-pressed to connect the solid polymer electrolytic film with the gas diffused electrode. In the initial stage of the hot press, the main component particle of the gas diffused electrode wetted by the solution of the solid polymer electrolyte is deeply bitten into the diffused electrode and the electrolytic film. Since the surface of the electrolytic film is softened by the solvent in the solid polymer electrolytic solution, the connecting area of the electrolytic film and the diffused electrode is increased. In the latter half of the hot press, the solvent is evaporated, and the main component particle of the diffused electrode is firmly solidified by the solid polymer electrolyte. Therefore, the contact area between the diffused electrode and the electrolytic film is increased, and the adhesion between the both is improved. |
