The present invention relates to an improvement of integrated fuel processor and fuel cell systems which improves stability of operation, simplifies control, and improves the heat recovery. According to the invention, a reforming zone is heated by indirect heat exchange with a first combustion effluent stream and provides a cooled first combustion effluent stream. The cooled combustion effluent stream is reheated in at least an additional combustion zone with at least a portion of the anode waste gas from the fuel cell to provide a reheated combustion effluent stream. The reheated combustion effluent stream is employed to further heat the reforming zone.
L'invention concerne un processeur de combustible intégré amélioré, et des systèmes de pile à combustible permettant d'améliorer la stabilité d'une opération, de simplifier une commande, et de perfectionner la récupération de chaleur. Selon invention, une zone de reformage est chauffée par échange indirect de chaleur avec un premier flux d'effluent de combustion, et produit un premier flux d'effluent de combustion refroidi. Ledit flux d'effluent de combustion refroidi est réchauffé au moins dans une zone de combustion supplémentaire contenant au moins une partie de résidus gazeux anodiques provenant de la pile à combustible afin de fournir un flux d'effluent de combustion réchauffé. On utilise ledit flux d'effluent de combustion réchauffé pour chauffer ultérieurement la zone de reformage.
