ABSTRACT:
The fuel cell system includes a fuel cell; a power conditioner that converts a cell power supplied from the fuel cell to a power corresponding to a load; a capacitor to which an excessive output power of the fuel cell is charged at the time of a low load operation and from which a power corresponding to the insufficient output power of the fuel cell is discharged at the time of a high load operation; a voltage detection means for detecting a voltage of the capacitor; and a control means that determines the low load operation or the high load operation, calculates an output power from the fuel cell to maintain the excessive power generated at the time of the low load operation within a space capacity of the capacitor, and controls the output power of the fuel cell not to exceed the calculated value.
