In a case where a load amount of a load is a predetermined value or less, a control device of an FC vehicle implements extremely low current control for performing power generation at an extremely low current below a lower limit current of an FC for normal operation. At the time of implementing the extremely low current control, upper and lower limit values of a target output voltage of the converter are set in correspondence with the extremely low current, and the output voltage of the FC is controlled to be within a range between the upper and lower limit values.
