<p><P>PROBLEM TO BE SOLVED: To prevent a gas fuel leaked from a gas fuel tank from entering into a passenger compartment. <P>SOLUTION: A hydrogen tank 30 is arranged at an approximately central part in a longitudinal direction above a roof 22 of a fuel battery mounting bus 20, an air-conditioning unit 60 is arranged at a front side of the hydrogen tank 30, a radiator 42 is arranged at a rear side respectively, and they are covered by a roof cover 50. An external air induction part 52 for inducing external air to an external air introduction port 60a of the air-conditioning unit 60 is provided on a front upper part of the air-conditioning unit on the midway of an upward inclination surface 50a at a front part of the roof cover 50, and a partition wall part 54 for partitioning the hydrogen tank 30 and the air-conditioning unit 60 is provided on a peripheral part at the hydrogen tank 30 side of the air-conditioning unit 60. According to this, since hydrogen leaked from the hydrogen tank 30 flows to a rear side by traveling wind, the leaked hydrogen can be prevented from being intruded into the occupant room through the external air introduction port 60a of the air-conditioning unit 60. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
