<P>PROBLEM TO BE SOLVED: To provide a fuel cell power generation system capable of efficiently collecting vapor contained in its exhaust air, and with both high overall efficiency and safety attained. <P>SOLUTION: In the fuel cell power generation system, exhaust gas discharged outside from an outflow cylinder 52 as remnant heat generated by power generation flows through a heating channel inside a heat exchanger for exhaust heat 90 to perform heat exchange between water in a hot-water pipe 92 and pure water in a pure water pipe 93 for an effective use of the exhaust gas. The pure water heated inside the pure water pipe 93 is supplied to a forward channel case 12 of a reformer 10. The water heated inside the hot-water pipe 92 is circulated to a hot-water storage tank. Condensed water liquefied from the exhaust gas inside a package of the heat exchanger for exhaust heat 90 is collected in a recovery water tank 95. The recovery water is stored in a reserve tank to be utilized as a part of high-purity pure water, and is supplied to the forward channel case 12 of the reformer 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
