<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of enhancing fuel consumption efficiency in a warming device, and to provide a method for controlling the fuel cell system. <P>SOLUTION: The fuel cell system decides whether exhaust gas temperature detected with a sensor is at calculated dew-point temperature or lower or not, and when the exhaust gas temperature exceeds the dew-point temperature (S6, No), and when coolant quantity can be increased (S7, Yes), the coolant quantity is increased (S10), and when increase of the coolant quantity is not possible (S7, No), and when mixed gas quantity can be reduced (S8, Yes), the mixed gas quantity is reduced (S9). When stack temperature is at warming target temperature or higher (S11, Yes), the stack temperature is controlled at dew-point temperature or higher, and the residual water is actively exhausted to the outside (S12). <P>COPYRIGHT: (C)2010,JPO&INPIT |
