PURPOSE:To enhance the efficiency of the whole generation system by cooling regenerators by means of a low-boiling-point medium used as a heat discharging loop, and providing a turbine driven with the said medium and a turbine driven with steam obtained through gas-liquid separation. CONSTITUTION:Power generation carried out by supplying to a fuel cell body 4, both a main fuel sent through a reformer 3, and air sent from a compressor 10 driven by a turbine 9. Here, in a steam cycle, power generation is performed by driving a turbine 18, and the exhaust steam is circulated through a cooling tower 19 so that the body 4 is cooled. On the other hand, in a low-boiling-point medium cycle, regenerators 11, 7 and 5, in that order, are cooled with a medium sent from a pump 21, and a turbine 23 is driven with the gas separated with a liquid-gas separator 22 so as to generate power, being followed by circulating the above gas through a cooling tower 24. As a result, the output of the generation can be increased by separating the steam cycle and the low-boiling-point medium cycle, and the efficiency of the whole system can be enhanced. |
