<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of expeditiously discharging moisture in an equipment arranged on a downstream side of a fuel cell during operation shutdown of the fuel cell. <P>SOLUTION: In the fuel cell system, a bypass piping 18 is installed in which one end is connected to more upstream side part of an air flow than the fuel cell 1 and a humidifier 11 in the piping 3 for air supply, and in which the other end 18b is on further downstream side of the fuel cell 1 in the piping 4 for air discharge, and connected to the upstream side part of a gas-liquid separator 16 and a muffler 17. At this time, for example, one end 18a of the bypass piping 18 is connected to the piping 3 for air supply via a three-way valve 19. Then, in stopping operation of the fuel cell 1, the three-way valve 19 is actuated and air sent out from an air pump 2 is made to flow into the bypass piping 18. <P>COPYRIGHT: (C)2007,JPO&INPIT |
