Abstract

La présente invention concerne un système de pile à combustible à oxyde solide qui comprend un échappement anodique qui circule à travers un passage de recyclage d’échappement anodique. La première partie de l’échappement anodique circule à travers un échangeur thermique à reformat, puis à travers un ventilateur de recyclage anodique (appelée flux de recyclage de l’échappement anodique). Un dispositif de commande de flux régule la distribution du flux de recyclage d’échappement anodique vers un orifice d’admission de désulfurant, fournissant de l’hydrogène au désulfurant, et un passage de combustible désulfurisé qui relie fluidiquement le désulfurant et le reformeur, fournissant de la vapeur au reformeur. La seconde partie de l’échappement anodique circule vers un échangeur thermique disposé entre un désulfurant et un reformeur afin de chauffer le combustible désulfurisé entrant dans le reformeur. Cette seconde partie de l’échappement anodique est alors brûlée dans un brûleur catalytique. Le courant d’évacuation du brûleur peut être mélangé à l’échappement anodique et utilisé pour préchauffer l’air de traitement fourni à une cathode de la pile à combustible.
