The invention relates to a liquid-cooled fuel cell battery and to a method for operating such a battery, whereby the starting behavior of the battery, in particular, is improved compared to prior art systems. According to the invention, the thermal capacity of the fuel cell battery is reduced upon starting such that at least a portion of the cooling liquid is removed from the cooling system when deactivated.
L'invention concerne une batterie de piles à combustible refroidie par liquide et un procédé pour faire fonctionner une telle batterie. En particulier le comportement au démarrage de cette batterie est amélioré, si l'on compare avec les systèmes connus, en ce que la capacité thermique de la batterie de piles à combustible au moment du démarrage est abaissée par le fait qu'au moins une partie du liquide de refroidissement est sortie du système de refroidissement lors de la mise hors circuit.
