<P>PROBLEM TO BE SOLVED: To provide a fuel cell co-generation system for raising cooling water temperature in a short time even if a temperature difference between stored hot water and cooling water is small and taking no time for starting up. <P>SOLUTION: The fuel cell co-generation system includes a fuel cell 11, a cooling water heat exchanger 13 arranged on a cooling water passage 16, a stored hot water passage 15 where the hot water performing heat exchange with the cooling water flows, a hot water storing tank 31, a stored hot water controlling means 33, a stored hot water temperature measuring means 36, a stored hot water flow volume adjusting means 38, a flow volume controlling means 37 for controlling the stored hot water flow volume adjusting means 38, and an exhaust gas heat exchanger 23 for performing heat exchange between the exhaust gas of fuel processing means 21, 22 and the stored hot water. The flow volume controlling means 37 reduces the flow volume of the stored hot water flowing in the stored hot water passage 15 by controlling the stored hot water flow volume adjusting means 38, in case the stored hot water temperature is a first given temperature or lower at starting up of the fuel cell 11. <P>COPYRIGHT: (C)2010,JPO&INPIT |
