A reformer fuel cell system consists of a plurality of components, that are a plurality of partial reformer systems (2, 3, 4; 8, 9; 10-15) forming a reformer (1) for the generation of a hydrogen-rich gas and a fuel cell (5) for the generation of electric current with use being made of the hydrogen-rich gas. Furthermore, a burner device (6) that is arranged outside of the reformer (1) and the fuel cell (5) is provided for the generation of a hot exhaust gas. An exhaust gas supply assembly (7) supplies the exhaust gas to at least two of the components wherein the exhaust gas supply assembly (7) defines the flow path of the exhaust gas such that the exhaust gas flows to and/or through the components according to the level of their particular operating temperature in descending temperature order. In this manner, it is easily possible to directly heat up the individual components to the level of their particular operating temperature in a selective manner.

L'invention concerne un système reformeur-cellule électrochimique comprenant plusieurs éléments, notamment plusieurs systèmes partiels (2, 3, 4; 8, 9; 10- 15) constituant un reformeur (1) pour produire des gaz riches en hydrogène, et une cellule électrochimique (5) générant du courant électrique en utilisant les gaz riches en hydrogène. Un dispositif brûleur (6) est en outre disposé à l'extérieur du reformeur (1) et de la cellule électrochimique (5) pour produire des effluents gazeux chauds. Un dispositif de conduite (7) des effluents gazeux les dirige vers au moins deux des éléments, ce dispositif de conduite (7) déterminant l'écoulement des effluents gazeux de telle sorte qu'ils s'écoulent vers et/ou à travers les éléments par ordre d'abaissement de température, en fonction de leur niveau de température de fonctionnement respectif. Il est ainsi possible de chauffer directement et de manière ciblée chaque élément pour le porter à son niveau de température de fonctionnement respectif.
