<P>PROBLEM TO BE SOLVED: To provide a mass-production direct fuel cell and a method of manufacturing the fuel cell at an advantageous cost. <P>SOLUTION: In this direct fuel cell, a fuel electrode 10 and an air electrode 12 are formed on the front and rear of a proton conductive part 6 opposite to each other by arranging a plurality of cells adjacent to each other, and the cells are electrically connected to each other. The proton conductive part 6 is formed by providing a proton conductivity thereto by graft-polymerizing monomer with ion-exchange groups after reaction active point is produced with a synthetic resin film 3 partially being irradiated with electron beam or radioactive ray. <P>COPYRIGHT: (C)2004,JPO |
