<P>PROBLEM TO BE SOLVED: To store generated-water dropped from an inner wall face and ion exchange resin of a case in a stop state of a fuel cell system, and prevent a drain valve from operation failure due to frozen generated-water. <P>SOLUTION: In a drain port 17 of a lower part of a gas-liquid separator case 11, the drain valve 18 is installed. On the bottom part of the case 11, a water storage part 20 is installed at a position lower than that of the drain valve 18. On the inner bottom face of the water storage part 20, an upward inclined face 20a is formed which is inclined upwardly toward the drain valve 18. On the inner bottom face of the water storage part 20, a downward inclined face 20b is formed which is inclined downwardly toward the upward inclined face 20a. On the upper part of the water storage part 20, a cover part 21 is installed. By this cover part 21, the upper part of the water storage part 20 is opened to an inlet 14 side, and a gas passage 22 connected to the drain valve 18 is formed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
