PURPOSE:To prevent the residence of condensed water bedewed in piping, check the water immersion accident of a unit cell or the flood fault accident of a reaction gas occurring due to the residence, and stabilize gas pressure by improving the structure of the outlet side piping of an offgas including produced water steam. CONSTITUTION:A drain pot 8 is connected to a low place of discharge system piping, including outlet collecting piping linked to an outlet manifold 3, to collect condensed water, and an discharging means 9 including a level switch and a drain valve is provided to discharge collected water outside without a gas pressure variation. Also a bursting tube and a discharge tube are added to the drain pot 8 and a water level is retained constant with the discharging means to also use the drain pot for a water sealing device to restrain the abnormal rise of gas pressure in the piping. |
