<P>PROBLEM TO BE SOLVED: To provide a fuel cell system which is effective in improving utilization efficiency of water supplied for steam reforming. <P>SOLUTION: The fuel cell system is provided with a hydrogen manufacturing device for forming a reformed gas rich in hydrogen by reforming a liquid material, a reformed gas inlet line L3 which introduces the reformed gas formed by the hydrogen manufacturing device 3 to a fuel cell stack 4, and a water recovery unit 23 which is separated and recovers water passing the hydrogen manufacturing device 3 without reacting from the reformed gas. The water recovery unit 23 has a vapor liquid separating chamber 25 and a standing tank 31. Even when non-reacted water flows out from the hydrogen manufacturing device 3, that water is separated and recovered from the reformed gas by the water recovery unit 23. As a result, recovered water can be reused as reforming water as required and utilized as cooling water of the fuel cell stack to make it effective for improving utilization efficiency. <P>COPYRIGHT: (C)2009,JPO&INPIT |
