<P>PROBLEM TO BE SOLVED: To facilitate discharge of water from a fuel cell system in stopping the fuel cell system. <P>SOLUTION: This fuel cell system 100 is provided with: a fuel gas supply part for supplying a fuel gas to a fuel cell 110 through a fuel gas supply pipe 132; and a fuel gas discharge part having a discharge valve 360 for discharging, to the outside of a piping system of the fuel cell system 100, the fuel gas discharged from the fuel cell 110 to a fuel gas discharge pipe 134. The fuel cell system 100 has a returning part for returning the fuel gas discharged from the fuel cell 110 to the fuel gas discharge pipe 134 to the fuel gas supply pipe 132. A fuel cell control part 400 executes a reverse flow mode for supplying the fuel gas from the fuel gas supply pipe 132 to the discharge valve 360 through the returning part by reversing the delivery direction of the gas of a circulation pump 340 arranged in the returning part in stopping the fuel cell system 100. <P>COPYRIGHT: (C)2007,JPO&INPIT |
