<P>PROBLEM TO BE SOLVED: To provide a cogeneration system capable of operating a fuel cell at a stabilized temperature even when the external output in the fuel cell fluctuates. <P>SOLUTION: The cogeneration system comprises a fuel cell generator having the fuel cell 10, a refrigerant circulation flow passage 2 with a refrigerant to cool the fuel cell 10 circulating therein, a waste heat exchanger 1 to receive the heat from the refrigerant passing through the fuel cell 10 in the refrigerant circulating flow passage 2, a thermal medium flow passage 14 in which the thermal medium receiving the heat from the refrigerant flows through the waste heat exchanger 1, and a hot water feeder with the thermal medium used as a heating medium. It has a load measuring means 7 for measuring the load of the fuel cell 10 based on at least one of the current load and the voltage load of the fuel cell 10 and adjusts the flow rate of the refrigerant according to the load measured by the load measuring means 7, and a means to adjust the flow rate of the thermal medium. <P>COPYRIGHT: (C)2003,JPO |
