PURPOSE:To simplify manufacturing processes by performing hot press with a film of ion exchange resin sandwiched between two electrode sheets each formed from a specific slurry, for bonding and integrating the electrode sheets and the film of ion exchange resin together. CONSTITUTION:A catalyst having platinum supported to carbon black, a solvent solution of ion exchange resin such as perfluorocarbon sulfonate resin, and a diluting solvent are mixed together to form a suspension. The suspension is accumulated on an electrode base made water-repellent and is filtered through the electrode base while being dispersed, to take the platinum-supporting catalyst and the ion exchange resin in the suspension into the electrode base so as to form electrode sheets. Next, hot press is carried out with a film of ion exchange resin serving as a solid high polymer electrolyte film sandwiched between the two electrode sheets so that the electrode sheets and the film of ion exchange resin are bonded and integrated together. Manufacturing processes can thus be simplified without use of polytetrafluoroethylene. |
