<P>PROBLEM TO BE SOLVED: To provide a fuel cell co-generation system preventing hot water from getting short capable of improving convenience. <P>SOLUTION: The co-generation system comprises a fuel cell 1; a cooling system for the fuel cell 1; an internal heat-conveyance medium heater 100; a heat utilizing part 16 for storing the heat recovered through the cooling system so as to utilize the same; a detection means 101A-101C for detecting the amount of heat remaining in the utilizing part 16; and a control device 201. The control device 201 determines whether the amount of the heat remaining in the utilizing part 16 is enough for raising the temperature of the fuel cell 1 up to its operation temperature or not, and depending on the result, raises the temperature of the fuel cell 1 up to operation temperature by supplying the remaining heat through the cooling system and/or by heating the cooling water in the cooling system by the internal heat-conveyance medium heater 100. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
