<P>PROBLEM TO BE SOLVED: To prevent water droplets from remaining in the vicinity of a flow adjustment means formed in a bypass passage for supplying air to an air exhaust passage. <P>SOLUTION: A hydrogen exhaust passage 13 for running hydrogen exhausted from a fuel cell, the bypass passage 15 for running the air from an air supply means by bypassing the fuel cell, and a drainage passage 17 for running condensed water drained from the fuel cell are respectively connected to the air exhaust passage 11 for running the air exhausted from the fuel cell. The connection parts thereof are formed in an air passage formation part 23a of a housing 23; and an idle-time flow adjustment valve 19 and a start-time flow adjustment valve 21 located on the bypass passage 15 are installed in a flow adjustment means installation part 23b of the housing 23. The idle-time flow adjustment valve 19 is installed on the upstream side of the start-time flow adjustment valve 21; a downward-tilting passage part 39 tilting downward in the vertical direction from the upstream side toward the downstream side is formed; and an upward-tilting passage part 41 is formed continuously thereto to open a bypass passage merging port 41a to the air exhaust passage 11. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
