<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of suppressing degradation of reforming efficiency. <P>SOLUTION: The fuel cell system (100) is provided with a fuel cell (60), a reforming means (51) to generate hydrogen by reforming reaction using a reformed fuel, a cathode off-gas supply means (80) to supply the cathode off-gas of the fuel cell to the reforming means, and an O/C control means (10, 80) to carry out a first control to control O/C so that S/C+O/C≥2 and O/C may be a first prescribed value or less when the load of the fuel cell fluctuates. <P>COPYRIGHT: (C)2008,JPO&INPIT |
