An output of a fuel cell is appropriately controlled. A required electric power generation amount calculation unit calculates and adds: an amount of electric power to be supplied to a traction motor; an amount of electric power to be supplied to an auxiliary apparatus; and an amount of electric power to be supplied to a battery and the traction motor in accordance with the charging and discharging of the battery, to calculate a required electric power generation amount. A lost electric power amount calculation unit calculates a lost electric power amount with reference to a lost electric power amount map based on: the required electric power generation amount; and a voltage increase ratio, output voltage and temperature in an FC converter. A lost electric power amount addition unit corrects the required electric power generation amount by adding the lost electric power amount to the required electric power generation amount. An electric power generation request unit outputs an instruction requesting power generation such that the electric power is generated in the required electric power generation amount after being corrected.
