<P>PROBLEM TO BE SOLVED: To provide a fuel cell system without unnecessary residue water remaining inside, through promotion of drainage inside an ion-exchange filter fitted to a gas liquid separator. <P>SOLUTION: The fuel cell system 1 includes a fuel cell stack 10, a gas liquid separator 20, a dilution unit 16, a hydrogen supply valve 11, a pump 13 as well as a motor 12 for the pump, a drain valve controller 15, and a fuel cell control device 14. From the fuel cell stack 10, offgas including unreacted hydrogen gas and reaction water flows into an offgas flow channel 42 to be guided to the gas liquid separator 20. The gas liquid separator 20 includes an ion-exchange filter 30 equipped with a guide member on a bottom face for promoting drop of droplets, and the reaction water is guided from a drain flow channel 44 to the dilution unit 16 to be drained therefrom 16, and discharged into the air. <P>COPYRIGHT: (C)2009,JPO&INPIT |
