The reformer-fuel cell system comprises a fuel cell to which a reformate gas is supplied for the production of electrical energy that is extracted in a reformer from hydrocarbon containing fuel through partial oxidation with air that is conveyed or led to the reformer as air inlet stream by a blower. A partial quantity of residual gases discharged from the fuel cell is repeatedly supplied by the reformate as recirculation stream of the reformer together with the air. The recirculation stream mixes the air inlet stream conveying the air in the reformer. The reformer-fuel cell system comprises a fuel cell to which a reformate gas is supplied for the production of electrical energy that is extracted in a reformer from hydrocarbon containing fuel through partial oxidation with air that is conveyed or led to the reformer as air inlet stream by a blower. A partial quantity of residual gases discharged from the fuel cell is repeatedly supplied by the reformate as recirculation stream of the reformer together with the air. The recirculation stream mixes the air inlet stream conveying the air in the reformer and is supplied through the blower to the reformer. The recirculation stream and/or the reformer-air inlet stream are conveyed through a suitable coordinated static throttle point or through a variable throttle point. The recirculation stream is conveyed before the introduction in the air inlet stream through a heat exchanger, which is formed through concentrically arranged tubes in which the recirculation stream and the reformer-air inlet stream are separately conveyed from one another. |
