SOLUTION: The hydrogen exhaust duct 30 is provided with a cylindrical element 45 leading gas into a first chamber 41 in the first chamber 41. A first gas discharge hole 37 is bored on an upper part of a first partition wall 36, and a second gas discharging hole 39 is bored on an upper part of a second partition wall 38 so as not to superimpose on the first gas discharging hole 37. A discharging portion 48 discharging gas from the second gas discharging hole 29 to the outside is bored on a wall of a third chamber 43. The bottoms of a second chamber 42 and the third chamber 43 are made to be a tilting bottom 51 tilting so as to descend from the second chamber 42 to the third chamber 43. Right and left discharging gutters 52, 52 are faced to a draing groove 23 of a cowl top 20. COPYRIGHT: (C)2004,JPO
