A control unit (100) disconnects, when the inner temperature of a fuel cell (40) does not reach a stationary temperature (step S26), a secondary cell (60) from an inverter (70) (step S28) and then controls the drive of a motor (80) (step S30) so that the motor (80) can consume power supplied from the fuel cell (40) while preventing the inverter (70) from generating a torque on the drive shaft (82) of the motor (80). Such controlling enables the inner temperature of the fuel cell to rise to a stationary temperature within the shortest possible time at starting the fuel cell.

Selon la présente invention, lorsque la température interne d'une pile à combustible (40) n'atteint pas une température stationnaire (étape S26), un organe de commande (100) déconnecte une pile secondaire (60) d'un convertisseur continu-alternatif (70) (étape S28) et commande l'entraînement d'un moteur (80) (étape S30) de façon que le moteur (80) peut consommer l'énergie fournie par la pile à combustible (40) tout en empêchant le convertisseur (70) de générer un couple sur l'arbre d'entraînement (82) du moteur (80). Ceci permet à la température interne de la pile à combustible de s'élever à un niveau stationnaire dans le plus court laps de temps possible lors de son démarrage.
