FUEL CELL SYSTEM AND VEHICLE

A fuel cell system includes a control section that: transmits a first current command value used to lower an output voltage of a fuel cell stack to a fuel cell converter when the output voltage becomes equal to or higher than a first voltage; transmits a second current command value used to boost the output voltage to the fuel cell converter when the output voltage becomes equal to or lower than a second voltage; stores the first current command value as a first storage value when the output voltage becomes equal to or lower than the second voltage; stores the second current command value as a second storage value when the output voltage becomes equal to or higher than the first voltage; and transmits a current command value that falls between the first storage value and the second storage value to the fuel cell converter.
