PURPOSE:To eliminate external water supply and water supply piping by providing a water-seal device also serves as a collecting water tank. CONSTITUTION:A water-seal device 40 also servable as a water collecting tank comprises a water collecting tank 47 for receiving the water condensed/separated by means of a gas/water separator 3 through a system 34 while containing the collected water 44 having the water level maintained constant by means of a liquid level adjusting section 45 constituted with an overflow discharge port and a communication pipe 48 having one end opening to the position of depth H in the collected water 44 and the other end coupled to the fuel gas supply systems shown by 12, 13, 14. Upon increase of the inner pressure of a fuel gas chamber 5, fuel gas is blown into the collected water through an opening of the communication pipe 48 at the time point when the inner pressure has exceeded over a head corresponding with the water depth H and the inner pressure of the fuel gas chamber 5 is maintained at approximately said head so that unexpected accident such as breakdown of a matrix 6 is prevented. While the level of the collected water 44 can be maintained constant from the overflow discharge port 45, resulting in elimination of external water supply and the piping therefor. |
