Fuel cell system and vehicle

A fuel cell system comprising:

• a fuel cell stack;
• a voltage detector that detects an output voltage of the fuel cell stack;
• a fuel cell converter that regulates the output voltage;
• and
• a control section that is configured to:
• transmit a first current command value used to lower the output voltage to the fuel cell converter in a case where the output voltage becomes equal to or higher than a first voltage that is an upper limit of an output voltage range;
• transmit a second current command value used to boost the output voltage to the fuel cell converter in a case where the output voltage becomes equal to or lower than a second voltage that is a lower limit of the output voltage range;
• store the first current command value as a first storage value in the case where the output voltage becomes equal to or lower than the second voltage;
• store the second current command value as a second storage value in the case where the output voltage becomes equal to or higher than the first voltage;
• and transmit the current command value as the first current command value or the second current command value to the fuel cell converter, the current command value being calculated by using the first storage value and the second storage value and falling between the first storage value and the second storage value.
