ABSTRACT:
In a mobile body, an intermittent operation to temporarily halt a cell operation is performed at a time when a request for power generation with respect to a fuel cell stack is less than a predetermined value, and recovery processing of a cell voltage is performed at a time when a cell voltage recovery processing executing condition is satisfied during the intermittent operation. When the mobile body is moving, a threshold voltage Vth1is set as the cell voltage recovery processing executing condition. When the mobile body is stopped, a threshold voltage Vth2is set as the cell voltage recovery processing executing condition. When the voltages are set so as to obtain a relation Vth1>Vth2, the cell voltage recovery processing can be limited during the stop of the mobile body.
