<P>PROBLEM TO BE SOLVED: To provide a fuel cell system that eliminates the need for a large three-way valve, and ensures a desired operating state, with a simple configuration and in a simple process. <P>SOLUTION: A fuel cell system 10 includes: a fuel cell 14 that has a plurality of laminated power generation cells 12; a fuel cell box 15 that houses the fuel cell 14; an oxidant gas supply device 32 that supplies oxidant gas to the fuel cell 14. The oxidant gas supply device 32 has: an air pump 34; an oxidant gas supply passage 40 that is connected to the air pump 34 and to an oxidant supply inlet of the fuel cell 14; a cooling passage 48 that branches off from the oxidant gas supply passage 40 and supplies the oxidant gas to the air pump 34 as cooling air; and a ventilation passage 50 that supplies the cooling air, which has cooled the air pump 34 and has been exhausted from the air pump 34, into the fuel cell box 15 as ventilation air. <P>COPYRIGHT: (C)2013,JPO&INPIT |
