摘要： A solid oxide fuel cell device comprises at least one solid oxide fuel cell comprising a cathode, an anode, and a solid electrolyte layer separating the cathode from the anode, in which the anode is fluidically connected to an anode supply line for the supply of fuel and an anode exhaust gas line for taking away the anode exhaust gas, and in which the cathode is connected to a cathode gas supply, wherein the anode exhaust gas line is fluidically connected to a storage line for the storing of carbon dioxide from the anode exhaust gas in a tank, in which there is connected at least one stage of a compressor for the compressing of the anode exhaust gas and one heat exchanger, downstream from the compressor, for the cooling of the anode exhaust gas compressed by the compressor. Downstream from the heat exchanger of the stage, a recirculation line branches off, emptying once again in the storage line upstream from the compressor, while an expansion valve is associated with the recirculation line for the expanding of the exhaust gas. A fuel cell vehicle having such a fuel cell device is also provided.
