Title
(EN) FUEL CELL SYSTEM
(FR) SYSTEME DE PILES A COMBUSTIBLE
Abstract
(EN) The present invention comprises a plurality of fuel cells connected to each other in series, and a reformer configured to reform raw fuel, wherein reformed fuel by the reformer is supplied to a first stage of the plurality of fuel cells, and the fuel cell on the first stage is provided with a methane reaction suppressing function which suppresses reaction of methane included in the reformed fuel to a larger extent than at least one fuel cell on a second and later stages. Suppressing temperature drop due to endothermic reaction in the fuel cell on the first stage can improve the efficiency of electric power generation of the fuel cell system having the plurality of fuel cells arranged in series.
(FR) La présente invention comprend une pluralité de piles à combustible connectées les unes aux autres en série, et un reformeur pour reformer le combustible brut. Le combustible reformé sortant du reformeur est transféré dans le premier étage de la pluralité de piles à combustible. Les piles à combustible dans le premier étage sont équipées d'une fonction d'inhibition de la réaction du méthane, de sorte que la réaction du méthane contenu dans le combustible reformé est plus fortement inhibée que dans au moins une des piles à combustible du deuxième étage ou des étages suivants. Dans le système de piles à combustible où la pluralité de piles à combustible sont disposées en série, l'efficacité de la production d'énergie peut être améliorée par la suppression d'une diminution de température provoquée par une réaction endothermique dans une pile à combustible du premier étage.
