CA 2662375
The invention relates to a method for starting a fuel cell system comprising a reformer (10) and a stack of fuel cells (12). The fuel (14) and the air (16) are supplied to the reformer as starting materials and a reformate (18) produced in the reformer is supplied to the stack of fuel cells. According to the invention, the air ratio characterising the fuel-air ratio of the starting materials supplied to the reformer (10) is varied in accordance with the temperature of the stack of fuel cells (12). The invention also relates to a fuel cell system.
L'invention concerne un procédé permettant de mettre en marche un système de piles à combustible comprenant un reformeur (10) et un paquet de piles à combustible (12). Du combustible (14) et de l'air (16) sont acheminés jusqu'au reformeur, à titre de produits de départ et un reformat (18) produit dans le reformeur est acheminé jusqu'à l'empilement de piles à combustible. Selon l'invention, il est prévu que le rapport combustible/air du coefficient d'air lambda caractérisant les produits de départ acheminés jusqu'au reformeur (10) varie en fonction de la température de l'empilement de piles à combustible (12). L'invention concerne en outre un système de piles à combustible.
