PROBLEM TO BE SOLVED: To provide a downsized, light-weight, and inexpensive fuel cell in which series connection is possible without using a high cost separator and an end plate. SOLUTION: A printed circuit board is used as the end plate, wiring for series-connecting a plurality of unit cells and a peripheral circuit such as a terminal for electrical connection to an external circuit are integrated with a fuel cell body, and the mechanical strength of the fuel cell body and the superior contact of an electrode are maintained. Furthermore, the surface roughness of a metal mesh is limited to a specific value, whereby, superior contact conductivity with a fuel cell electrode is provided even under relatively low pressure.
