<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of improving scavenging efficiency by suppressing temperature fall in the fuel cell in scavenging. <P>SOLUTION: The fuel cell system 1 comprises a fuel cell 10 and a scavenging means (a compressor 20 and a control device 4) to discharge moisture in the fuel cell 10 to the outside by supplying a scavenging gas into the fuel cell 10. A circulation route (an air supply passage 21, an air exhaust passage 22, and an air passage inside the fuel cell 10) to merge the exhaust gas discharged to the outside by the scavenging means into the scavenging gas is formed, and a dehumidifying means (desiccator 23) to remove moisture of the gas flowing in the circulation route is provided, and the whole amount of exhaust gas is merged into the scavenging gas. <P>COPYRIGHT: (C)2007,JPO&INPIT |
