  • a fuel cell;

    a load which operates owing to a power of the fuel cell;

    a first voltage conversion device which is provided between the fuel cell and the load and which converts an output of the fuel cell into a voltage to supply the voltage to the load;

    an operation control device for operating the fuel cell at a low-efficiency operation point having a power loss larger than that of a usual operation point in a case where predetermined conditions are satisfied; and

    a voltage conversion control device for controlling a voltage converting operation of the first voltage conversion device based on the operation point of the fuel cell and a driving voltage of the load.
