<P>PROBLEM TO BE SOLVED: To provide a fuel cell system for restraining overdrying inside a fuel cell in starting power generation of the fuel cell. <P>SOLUTION: The fuel cell system includes a fuel cell 1 having a cooling path 10 through which cooling medium passes at regular operation and generating power by reaction gas, a cooling medium supply path 2 supplying the cooling medium to the cooling path 10 of the fuel cell, a heating part 3 heating the cooling medium at the cooling medium supply path 2 and controlling the temperature of the cooling medium, and a control device 4. When a temperature of reaction gas supplied to the fuel cell 1 is Tg in the control device 4, in starting power generation of the fuel cell 1, the control device 4 restrains temperature rise of the temperature Ts of the fuel cell 1 due to controlling the temperature rise of the cooling medium by controlling the heating part 3 corresponding to the temperature rise speed of the temperature Tg of the reaction gas, and carries out overdry restraint control for restraining dryness inside a stack 1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
