<P>PROBLEM TO BE SOLVED: To provide a gas exhaustion structure capable of simplifying a structure of a fuel cell module and effectively controlling temperature of the module. <P>SOLUTION: The fuel cell stack formed by laminating a large number of power generating cells is housed in a heat insulation housing, and power generation reaction is generated by supplying reaction gas to the fuel cell stack at operation. A gas exhaustion structure 30, used for the fuel cell module exhausting exhaust gas generated by the power generation reaction outward, has a heat exchanger 20 using the exhaust gas introduced from the fuel cell stack as a heat source, and a bypass flow passage 22 exhausting the introduced exhaust gas outward while detouring the heat exchanger 20. <P>COPYRIGHT: (C)2007,JPO&INPIT |
