<P>PROBLEM TO BE SOLVED: To provide a fuel cell system preventing erroneous operation of a meter with a simple structure. <P>SOLUTION: The fuel cell system 1 includes: a reforming part 25 reforming material gas m1 and forming reformed gas g mainly containing hydrogen; a fuel cell 30; a combustion part 23 introducing and burning material gas m2; the meter 15 detecting fluctuation of a flow rate of the material gas m introduced in the reforming part 25 and combustion part 23; and a control device 36. The meter 15 takes safety measures when the fluctuation of the flow rate of the material gas m is within a predetermined range over a first predetermined time. When a continued operation time of the fuel cell 30 (or an opened time of a common shutoff valve 67 or reforming part shutoff valve 65) passes over a predetermined time shorter than the first predetermined time from a reference point of time, the control device 36 fluctuates a flow rate of the material gas m2 supplied to the combustion part 23 beyond the predetermined range. <P>COPYRIGHT: (C)2011,JPO&INPIT |
