Abstract: A battery and a load device are connected to a fuel cell stack. Electric power is supplied from the battery to fuel cell auxiliary equipment. A controller of a fuel cell system has stored therein a desired output of the fuel cell stack.

The controller determines a requested output, which is an output requested for the fuel cell stack, based on the predicted auxiliary equipment power consumption and the estimated input and output power. The controller determines an operating point of the fuel cell stack based on the desired output. The load device controls its operation so that the difference between the requested output and the desired output becomes zero.
