<P>PROBLEM TO BE SOLVED: To provide a fuel cell power generator with condensed water hardly contaminated during start-up. <P>SOLUTION: The fuel cell power generator is provided with a reformer 1 obtaining hydrogen-rich gas by burning raw fuel with a burner 2; a fuel cell main body 10 having a fuel electrode and an air electrode, generating electric energy by supplying hydrogen-rich gas from the reformer 1 to the fuel electrode and supplying air to the air electrode; an exhaust heat collecting heat exchanger 4 guiding combustion exhaust gas of the burner 2 and exhaust gas of the cell air electrode of the fuel cell main body 10 to its inside through a burner exhaust gas line and an air electrode exhaust gas line, collecting the water contained in the combustion exhaust gas of the burner 2 and exhaust gas of the cell air electrode; a water heater 12 storing hot water collected at the exhaust heat collecting heat exchanger 4; a hot water circulation line 19 installed between the water heater 12 and the exhaust heat collecting heat exchanger 4, circulating hot water between the above two; and a hot water circulation pump 5 installed at the hot water circulation line 19 for stopping circulation of hot water inside the exhaust heat collecting heat exchanger 4 when the raw fuel is burnt at the burner 2 at start-up of the fuel cell main body 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
