The control device is configured so that when a temperature of the fuel cell at the time of start of power generation of the fuel cell is less than a standard temperature, it makes the fuel cell generate power so that the amount of heat generation of the fuel cell accompanying the power generation loss becomes a first amount of heat generation and so that when a cumulative value of current of a time period during which the fuel cell is made to generate power so that the amount of heat generation becomes the first amount of heat generation is equal to or greater than a predetermined cumulative value, it makes the fuel cell generate power so that the amount of heat generation becomes a second amount of heat generation larger than the first amount of heat generation.
