PURPOSE:To increase the reaction efficiency and to realize a high electric power by connecting a solid high polymer electrolyte membrane and a gas diffusion electrode in the condition to soften or solve the soild high polymer electrolyte membrane in alcohol. CONSTITUTION:Hydrophile reaction membranes 3A and 3B are formed at the ratio 0.7:7:3 of platinum of the mean particle diameter 50Angstrom , a hydrophile carbon black of the mean particle diameter 450Angstrom , and polytetrafluoroethylene of the mean particle diameter 0.3mum, and hydrophobic gas diffusion membranes 4A and 4B are formed at the ratio 7:3 of a hydrophobic carbon black of the mean particle diameter 420Angstrom and polytetrafluoroethylene of the mean particle diameter 0.3mum. They are superposed and rolled, and Pt 0.56mg/cm<2> is held at the hydrophile reaction membrane side in the hydrogen chloroplatinate oxidization and reduction method to make into gas diffusion electrodes 2A and 2B. A perfluorosulfuric acid polymer membrane of the thickness 0.17mm is held between two sheets of such diffusion electrodes 2, and a hot press is applied in a mixture solution of the ratio 1:1 of isopropyle alcohol and a pure water in the condition at 120 to 130 deg.C and 60kg/cm<2> to form a connecting body. In such a way, the connection is made easily, and the connecting body of a thin membrane thickness and a low movement resistance of H<+> can be obtained. |
