Abstract
(EN)
A fuel cell system in which hydrogen is supplied from a hydrogen storage tank having a hydrogen storage alloy packed therein to a fuel cell, and in which the heat medium after cooling of the fuel cell is used to heat the hydrogen storage alloy at hydrogen emission from the hydrogen storage alloy. Charging of hydrogen gas in the hydrogen storage tank is carried out at a temperature not lower than the highest temperature reached by the heat medium during steady operation of the fuel cell under a pressure not lower than the equilibrium pressure of the hydrogen storage alloy. Emission of hydrogen from the hydrogen storage alloy is carried out at a temperature lower than the temperature of hydrogen storage alloy at the completion of the above charging.

La présente invention concerne un système de pile à combustible où l’hydrogène est approvisionné à partir d’un réservoir de stockage d’hydrogène qui comprend un alliage de stockage d’hydrogène vers une pile à combustible, et où le milieu chauffant est utilisé, après refroidissement de la pile à combustible, pour chauffer l’alliage de stockage d’hydrogène pour obtenir une émission d’hydrogène à partir de l’alliage de stockage d’hydrogène. Le chargement de l’hydrogène gazeux dans le réservoir de stockage d’hydrogène se fait à une température égale ou supérieure à la température la plus élevée atteinte par le milieu chauffant durant le fonctionnement stable de la pile à combustible sous une pression égale ou supérieure à la pression d’équilibre de l’alliage de stockage d’hydrogène. L’émission d’hydrogène à partir de l’alliage de stockage d’hydrogène s’effectue à une température inférieure à la température de l’alliage de stockage d’hydrogène à la fin du chargement ci-dessus.
