Abstract:
A fuel cell system including: a fuel cell; a voltage sensor that measures output voltage of the fuel cell; a converter that boosts the output voltage; and a control unit that controls the converter using a duty ratio including a feedforward term and a feedback term, the feedforward term being set to perform feedforward control, the feedback term being set to perform feedback control, wherein when the control unit causes the converter to boost the output voltage, and when the feedforward term calculated by specified Expression I exceeds an upper limit calculated by specified Expression II, the control unit causes the converter to boost the voltage output from the fuel cell with the duty ratio including the upper limit and the feedback term.

Claim (Index 3):
The fuel cell system according to  claim 1 , wherein\n in a discontinuous mode involving intermittent application of electric current to a reactor of the converter, the feedforward term is calculated by Expression III below: D_FF = 2 \u00b7 L \u00b7 f \u00b7 VH - VL VH \u00b7 VL \u00b7 ILtgt ( III ) L: inductance of the reactor f: switching frequency ILtgt: a target value of effective electric current VL (V): a measurement value of the output voltage of the fuel cell by the voltage sensor VH (V): a measurement value of the output voltage of the fuel cell converter D_FF: the feedforward term and\n in a continuous mode involving continuous application of electric current to the reactor, the feedforward term is calculated by Expression 1.
