摘要：<P>PROBLEM TO BE SOLVED: To stop power generation after a hot water storage tank becomes full heat-storage state even in a fuel cell power generation system having no radiator. <P>SOLUTION: The fuel cell power generation system includes a cooling heat exchanger 4 cooling gas passing through a passage from a reformer 2 to a fuel cell 5; a hot water circulation pump 9 installed in midway in circulation piping 52 returning from the lower part of a hot water storage tank 8 to the hot water tank 8 through the low temperature side of the cooling heat exchanger 4; water supply piping 51 connecting an outside water source to the circulation piping 52 on the downstream side than the hot water storage tank 8 but on the upstream side than the cooling heat exchanger 4; drain piping 53 branched from the circulation piping 52 on the downstream side than the cooling heat exchanger 4 but the upstream side than the hot water storage tank 8, and to which a drain control valve 16 is installed; and a control device 11. The control device keeps the drain control valve in an opened state when the temperature of water for supplying from the hot water storage tank 8 to the cooling heat exchanger 4 is higher than the prescribed temperature during cooling down after the power generation of the fuel cell 5 is stopped. <P>COPYRIGHT: (C)2010,JPO&INPIT
