<P>PROBLEM TO BE SOLVED: To provide a fuel cell system whereof a lifetime is improved and good power generating performance is secured for a long period of time, and operation is made possible even when a valve becomes out of order. <P>SOLUTION: This fuel cell system is equipped with an entrance shut valve 20 provided in a main route 30 forming an oxidation gas supply passage 14, a humidifier bypass valve 18 provided in a humidifier bypass route 32 forming the bypass of the main route 30, and a control part. The control part cuts off the gas upstream side of the passage on the cathode side electrode side of a fuel cell stack 12 by cutting off both of the entrance shut valve 20 and the humidifier bypass valve 18, when the fuel cell stack 12 stops generating power. <P>COPYRIGHT: (C)2008,JPO&INPIT |
