<P>PROBLEM TO BE SOLVED: To improve the starting properties of a fuel cell system having fuel cells. <P>SOLUTION: The fuel cell system 10 is provided with an exhaust gas guide-in channel 70, consisting of an exhaust gas guide-in channel part 72 enveloping a generated water circulation tube path 50 and a branched tube path 52 that serves as a tube path at the reuse of the generated water of a generated water storage tank 62, and an exhaust gas guide-in storage chamber part 74 formed as a region including a generated water discharge tube path 60 for discharging the generated water to the outside from the fuel cell 40. There is a heat exchanger 78 over the exhaust gas guide-in storage chamber part 74 and the generated water storage tank 62. If there is freezing of generated water or there is possibility of the occurrence of freezing of the generated water at a water system of the generated water in the initial stage of operation of the system, exhaust gas, generated from combustion of methanol at a heating unit of a reforming device 20, is introduced into the exhaust gas guide-in channel 70. As a result of this, thermal energy of the exhaust gas is given to the frozen generated water in the generated water circulation tube path or the like. <P>COPYRIGHT: (C)2007,JPO&INPIT |
