<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of preventing the freezing of an anode gas channel. <P>SOLUTION: A fuel cell system 10 includes an anode gas channel 23, a cathode gas channel 24, a fuel cell 11, and discharge valves 51 and 52 for discharging fluid in the anode gas channel to the outside. The system includes a control part 45 for periodic fluid replacement which controls an anode gas supply part 30 and a discharge valve, and periodically opens the discharge valve while supplying an anode gas to the anode gas channel. The control part includes a low temperature state determining part which determines whether or not it is in a low temperature state after a fuel cell is triggered. When the low temperature state determining part determines it is in the low temperature state, a fluid discharge amount from the discharge valve is increased to be larger than a fluid discharge amount during the periodic fluid replacement, so that the fluid replacement in the anode gas channel is executed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
