<P>PROBLEM TO BE SOLVED: To appropriately maintain the amount of reaction gas supplied to a fuel cell even if supply of the reaction gas during the drive frequency of a valve device has failed. <P>SOLUTION: A fuel cell system 1 includes a fuel cell 10; a gas supply passage 31 for supplying reaction gas to the fuel cell 10; a valve device 35 arranged in the gas supply passage 31 and driven by a predetermined drive cycle; a control device 4 which controls drive of the valve device 35 so that the reaction gas supplied to the fuel cell 10 is in a target gas state; and a sensor 43 which measures a gas state of the reaction gas at the downstream side of the valve device 35. When it is detected that the difference between the target gas state and the gas state measured by the sensor 43 exceeds a predetermined value, the control device 4 drives the valve device 35 separately from the predetermined drive cycle. <P>COPYRIGHT: (C)2009,JPO&INPIT |
