Abstract
A fuel cell includes a solid polymer ion exchange membrane having a thickness which is set to be within a range of 20 &mgr;m to 60 &mgr;m. The fuel cell comprises a fuel gas flow passage for supplying a non-humidified fuel gas from a side of a first surface of the ion exchange membrane, and an oxygen-containing gas flow passage for supplying a non-humidified oxygen-containing gas from a side of a second surface of the ion exchange membrane. A portion of the fuel gas flow passage, which is disposed in the vicinity of a fuel gas inlet, is arranged closely to a portion of the oxygen-containing gas flow passage disposed in the vicinity of an oxygen-containing gas outlet. Accordingly, the oxygen-containing gas and the fuel gas can be supplied without humidification, and it is possible to perform efficient and smooth operation.
