<P>PROBLEM TO BE SOLVED: To provide a silencer having structure narrowing a zone where a sound absorbing material 45 therein contains more water. <P>SOLUTION: The silencer 10 for a fuel cell includes a storage part 14 having the sound absorbing material filled between an outer shell 12 and an inner pipe 30, and a water drain part 16 facing the vertical lower side 38 of the inner pipe 30 and having the sound absorbing material 45 not filled between the outer shell 12 and the inner pipe 30. The water drain part 16 receives water flowing in the outer shall and drains the water to the outside of the outer shell 12. Even if the water drain part 16 receives water flowing in the outer shell 12, the sound absorbing material 45 in the silencer 10 does not suck nor contain the water from the water drain part 16 since the sound absorbing material 45 is not filled in the water drain part 16. <P>COPYRIGHT: (C)2007,JPO&INPIT |
