<P>PROBLEM TO BE SOLVED: To optimally control the dew point of a reaction gas to be supplied to a fuel cell. <P>SOLUTION: The fuel cell system (10) includes a fuel cell (80) receiving the supply of the reaction gas and performing a power generation, a reaction gas supply unit (60) for supplying the reaction gas to the fuel cell (80), a humidifier (63) for humidifying the reaction gas, a gas temperature control means (20) for controlling the temperature of the reaction gas, and a dew point measuring unit (64) for measuring the dew point of the reaction gas. The gas temperature control means (20) controls the dew point of the reaction gas by heating or cooling the reaction gas based on the dew point of the reaction gas measured by the dew point measuring unit (64). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
