Abstract
For controlling operation of a vehicle-mounted fuel cell stack, a determination is made as to whether consumed electric power, measured during travel of a vehicle, is greater than standard electric power. If so, a generated electric power amount (output) of a fuel cell stack is judged to be great, in which case not only a fan is activated for rotation but also an air allocation mechanism is operated in an opening direction. In an alternative, information of a traveling velocity is also taken into account. Namely, when the fuel cell stack is operated in a vehicle traveling state where the vehicle's traveling velocity does not increase despite an increase in the electric power output from the cell stack, not only the fan is activated for rotation but also the air allocation mechanism is operated in the opening direction, so that a cooling-air flow amount can be increased.
