<P>PROBLEM TO BE SOLVED: To provide a fuel cell system which detects leakage of a combustible gas even during power generation and is operated safely. <P>SOLUTION: The fuel cell system includes a fuel treatment unit 1 having a reformer to produce a fuel gas including hydrogen using a raw material gas, a fuel cell 5 which generates power using the fuel gas and an oxidant gas, a combustor 2 which burns the gas passing the fuel treatment unit 1 and supplies heat to the reformer, a temperature detector 11 which detects temperature of the reformer, a raw material gas supplier 9 which supplies the raw material gas, a controller 7 which feedback controls the raw material gas supplier 9 so that the detection temperature of the temperature detector 11 may be a prescribed temperature, and an abnormality annunciator which informs the abnormality fact when the flow-rate of the raw-material gas added by the feedback control by the controller 7 is a prescribed threshold or more against the raw-material gas flow-rate target value defined according to the power generation amount of the fuel cell 5. <P>COPYRIGHT: (C)2009,JPO&INPIT |
