<P>PROBLEM TO BE SOLVED: To provide a fuel cell system in which cooling of a reaction gas by a fuel cell is suppressed, the concentration of steam contained in the reaction gas is suppressed, and accordingly, flooding is suppressed inside the fuel cell, when starting power generation of the fuel cell. <P>SOLUTION: The fuel cell system has the fuel cell 1, to generate electric power by the reaction gas; a supply passage 2 to supply the reaction gas to the fuel cell 1; a humidifier 4 which is installed at the supply passage 2 and humidifies the reaction gas, before being supplied to the fuel cell 1; and a reaction gas temperature adjusting element to adjust temperature of the humidifier 4 so as to be able to adjust the temperature of the reaction gas before being supplied to the fuel cell 1. When power generation of the fuel cell 1 is started, a control device 5 controls the reaction gas temperature adjusting element 63 so that the temperature of the reaction gas can be maintained lower than that of the fuel cell 1, and controls the temperature of the reaction gas, before being supplied to the fuel cell 1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
