Abstract:
A control method for fuel cell system capable of executing an idle stop operation is provided, in which operation power generation of a fuel cell is selectively stopped according to a required output of a load and cathode gas is intermittently supplied to the fuel cell during an operation stop. An upper limit value and a lower limit value of an output voltage of the fuel cell during the idle stop operation is set, the cathode gas is intermittently supplied with the output voltage of the fuel cell set at a value between the upper limit value and the lower limit value, a wet/dry state of the fuel cell is detected, a wet/dry appropriate range in which the wet/dry state of the fuel cell during the idle stop operation is appropriate is set, and it is determined whether or not the detected wet/dry state of the fuel cell is within the set wet/dry appropriate range. If the wet/dry state of the fuel cell is determined to be outside the set wet/dry appropriate range, the output voltage of the fuel cell is reset, and the cathode gas is intermittently supplied with the output voltage of the fuel cell set at a value between the upper limit value and lower limit value of the reset output voltage.

Claim (Index 21):
A fuel cell system capable of executing an idle stop operation to selectively stop power generation of a fuel cell according to a required output of a load and intermittently supply cathode gas from a cathode gas supplying device to the fuel cell during an operation stop, comprising:\n a wet/dry state detection unit configured to detect a wet/dry state of the fuel cell; an output voltage upper/lower limit value setting unit configured to set an upper limit value and a lower limit value of an output voltage of the fuel cell during the idle stop operation; a wet/dry appropriate range setting unit configured to set a wet/dry appropriate range in which the wet/dry state of the fuel cell during the idle stop operation is appropriate; a wet/dry appropriate range determination unit configured to determine whether or not the wet/dry state of the fuel cell detected by the wet/dry state detection unit is within the wet/dry appropriate range set by the wet/dry appropriate range setting unit; an output voltage resetting unit configured to reset at least one of the upper limit value or the lower limit value of the output voltage of the fuel cell if the detected wet/dry state of the fuel cell is determined to be outside the set wet/dry appropriate range by the wet/dry appropriate range determination unit; and a control unit configured to intermittently supply the cathode gas from the cathode gas supplying device with the output voltage of the fuel cell set at a value between the upper limit value and the lower limit value of the output voltage after the resetting if the output voltage resetting unit resets the output voltage of the fuel cell.
