PURPOSE:To increase the fuel utilization factor, improve the power generation efficiency, separate carbon dioxide, and perform a stable operation for a long time by feeding the gas mainly consisting of separated carbon dioxide to an oxidation gas system and feeding the discgarged fuel gas mainly consisting of hydrogen to a fuel gas system. CONSTITUTION:The fuel 11 mainly consisting of hydrogen carbide is fed to a fuel processing device 1 together with the discharged fuel gas 18 mainly consisting of hydrogen recycled from a carbon dioxide separator 8 and the steam fed from outside and is converted into the fuel gas 13 mainly consisting of hydrogen and carbon monoxide. This fuel gas 13 contains a large quantity of hydrogen recycled from the carbon dioxide separator 8 in addition to the hydrogen and carbon monoxide generated from the fed fuel 11 and steam 12, thereby the fuel gas 13 abundant in a reaction material can be fed to a fuel cell 3. Accordingly, the average unit cell voltage is improved, and the whole system can be operated with a high fuel utilization factor. The fuel gas 14 discharged from the fuel cell 3 is adjusted on an adequate temperature by a heat exchanger 10 then is fed to a carbon monoxide converter 6. |
