Disclosed is a fuel cell system capable of stabilizing the power generation state of a fuel cell for a period of transition from a power generation stop state during an intermittent operation or the like to a usual operation. The fuel cell system supplies a fuel gas from a fuel supply source to a fuel cell to generate a power, and comprises output limit means for limiting the output of the fuel cell after shift from the power generation stop state of the fuel cell to a power generation state. The output limit means subtracts the flow rate of the fuel gas used to recover the pressure of the fuel gas in the power generation stop state to the pressure of the fuel gas in the power generation state from the total flow rate of the fuel gas supplied from the fuel supply source after the shift from the power generation stop state to the power generation state, to calculate the flow rate of the fuel gas actually supplied to the fuel cell after the shift from the power generation stop state to the power generation state, thereby limiting the output of the fuel cell by use of an output current value corresponding to the calculated flow rate as an upper limit. |
