<P>PROBLEM TO BE SOLVED: To make an discharge circulating gas possible to be utilized to heat a heating medium without causing the boiling of the heating medium, high-pressurizing of the heating medium passage, and degeneration or the like of the heating medium. <P>SOLUTION: At a cold-start, the fuel cell system is warmed up by giving heat of a high-temperature combustion gas generated by a combustor 5 to the heating medium to control the temperature of the fuel cell system with a heat exchanger 6, and discharge is carried out via a gas discharge three-way valve 21 to discharge a high-temperature combustion gas generated by the combustor 5 without passing through the heat exchanger 6 in carrying out hydrogen purge. <P>COPYRIGHT: (C)2004,JPO |
