<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of preventing failure of a reformer and evading operation shutdown of a fuel cell in the case there is abnormality (failure) in a water supply means. <P>SOLUTION: This is the fuel cell system 1 equipped with the fuel cell 1, the reformer 4 in order to supply a reformed gas, a reformed gas supply means 5 in order to supply the reformed gas 4 and water, an oxygen containing gas supply means 6, and a water supply means 8 in order to supply water or vapor from a water tank 7, in which the oxygen containing gas supply means is shut down at the time of normal operation. In the case a water supply amount to the reformer 4 becomes over a preset prescribed amount or equal to or less than the prescribed amount, by being equipped with a control means 9 of switching the water supply means 8 to the oxygen containing gas supply means 6 or using both supply means at the same time, even in the case there is the abnormality in the water supply means 8, a stable reforming reaction can be carried out and the failure of the reformer 4 can be prevented, and operation shutdown of the fuel cell 2 can be evaded. <P>COPYRIGHT: (C)2008,JPO&INPIT |
