PURPOSE:To realize an ion-exchange membrane fuel cell wherein a three-phase interface is enlarged to display higher performance by sufficiently giving ion- exchange membrane resin to the inside of an electrode. CONSTITUTION:From a process of adding ion-exchange membrane resin and carbon fine powder of carrying a noble metal catalyst to a water solution of low class saturated primary alcohol to form dispersion liquid of ion-exchange membrane resin and carbon fine powder catalyst and from a process of crushing after filter-drying this dispersion liquid, this catalyst for a cell is obtained, and this catalyst and carbon fine powder, water repellency treated by fluorinated carbon resin, are mixed and pressure molded on a conductive electrode substrate. In this way, the ion-exchange membrane fuel cell of displaying high discharge performance is obtained. |
