<P>PROBLEM TO BE SOLVED: To prevent retention of moisture on a merging part downstream side between an air exhaust passage and a hydrogen exhaust passage. <P>SOLUTION: A gas-water separation means 15 is formed in a merging part to the air exhaust passage 11 of the hydrogen exhaust passage 13 connected to a fuel cell. Hydrogen containing moisture and having entered into a hydrogen entrance-side space 23a of a hydrogen introduction space 23 via a hydrogen introduction port 29 from the hydrogen exhaust passage 13 collides with a wall part 21 to separate moisture from hydrogen. Water is accumulated in a lower part as accumulated water W, and hydrogen flows into a hydrogen exit-side space 23b through a hydrogen running space 27 under a partition wall 25 and flows out to an air passage part 19 communicating with the air exhaust passage 11 via a hydrogen diffusion hole 31. When the level of the accumulated water W rises, a float 35 is lifted to drain the accumulated water W from a drain outlet 33a. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
