Abstract
Through holes for flow paths of the fuel cell are formed in a thermoplastic polymer film by a process selected from a group consisting of laser drilling, etching and lithography, an inner side surface of the thermoplastic polymer film is coated with a metal layer, and the through holes are filled with a fuel diffusion material and a catalyst to provide an anode. The procedure is repeated to provide a cathode. Then, the anode and the cathode are placed to oppose each other. A cation conducting polymer membrane is disposed, between the anode and the cathode, and the anode, the cation conducting polymer membrane and the cathode are hot-pressed.
