<P>PROBLEM TO BE SOLVED: To realize energy-saving by effectively utilizing heat of an exhaust gas, while making the reforming water to supply to a reforming water tank from the outside as small as possible. <P>SOLUTION: The fuel cell system is provided with a reforming part 12 to generate a hydrogen-contained gas from a fuel gas A using a reformed water B stored in a reformed water tank 1, a condensation part 4 to condense steam contained in an exhaust gas D of the fuel cell part 3, a condensed water recovery passage 5 to recover the condensed water E condensed by the condensation part 4 and supply to the reforming water tank 1, a heat storage liquid circulation means 24 which supplies heat storage liquid C taken out of a heat storage tank 23 to the condensation part 4 and circulates the heat storage liquid C in a manner to return to the heat storage tank 23, and a radiator 29 which can implement heat radiating action to radiate heat from the heat storage liquid C taken out of the heat storage tank 23 and before supplying to the condensation part 4. The condensation part 4 is structured to condense the steam by heat exchange of the steam contained in the exhaust gas D and the heat storage liquid C. <P>COPYRIGHT: (C)2009,JPO&INPIT |
