<P>PROBLEM TO BE SOLVED: To provide a fuel cell system enabling further downsizing while being compatible with exhaust heat recovery and fluid recovery. <P>SOLUTION: A fuel cell system 1 comprises a reformer 2 generating a reformed gas by reforming a raw fuel; a fuel cell stack 3 generating power using the reformed gas generated by the reformer 2; and first and second heat exchangers 5 and 6 exchanging heat between an exhaust gas and exhaust heat recovery water by introducing an exhaust gas discharged from a hot module 4 with vapor. The first heat exchanger 5 is disposed on an exhaust gas line L2 so as to be horizontal in a longitudinal direction, and the second heat exchanger 6 is disposed on downstream of the first heat exchanger 5 on the exhaust gas line L2 so as to be vertical in a longitudinal direction. In the second heat exchanger 6, a vapor in an exhaust gas cooled by the first heat exchanger 5 is condensed by heat exchange, and condensed water is recovered. <P>COPYRIGHT: (C)2012,JPO&INPIT |
