Abstract

Hydrogen tanks (30) are disposed approximately in the center along the longitudinal direction on roof (22) of fuel cell mounting bus (20). Air conditioner unit (60) is disposed in front of the hydrogen tanks (30) and radiator (42) in the rear thereof, and they are covered by roof cover (50). Outside air guide part (52) for guiding of outside air to outside air intake port (60a) of the air conditioner unit (60) is disposed in an intermediate position of rising slope surface (50a) in the front part of the roof cover (50) and in an upper region in front of the air conditioner unit (60). Bulkhead part (54) for isolating the hydrogen tanks (30) from the air conditioner unit (60) is disposed on the periphery of the air conditioner unit (60) on its side of hydrogen tanks (30). By virtue of this structure, any hydrogen having leaked out from the hydrogen tanks (30) is caused to flow backward by wind generated by running, so that any permeation of leaked hydrogen into the cabin through the outside air intake port (60a) of the air conditioner unit (60) can be avoided.

Description

technical field [0001] The present invention relates to vehicles, and more particularly, to vehicles that run using power from a power source. Background technique [0002] Conventionally, such a vehicle is known as a vehicle equipped with an engine using a gaseous fuel such as CNG (compressed natural gas), or the like. For example, when such a vehicle is used as a mainline bus, a gas fuel tank has been proposed to be provided on the roof in order to lower the pedals to meet barrier-free viewpoints of the elderly (for example, refer to Patent Document 1). [0003] Furthermore, as a cooling method for the power source of such a vehicle, a fuel cell device in which a fuel cell as a power source and a radiator are connected through a cooling pipe and the radiator is placed at a position exposed to the outside air has also been proposed ( For example, refer to patent document 2). For example, when such a device is mounted on a bus, the radiator is disposed under the wings of t...

Problems solved by technology

In this case, since most of the space on the roof is occupied by the gas tank, it may be difficult to place the radiator at a position where the driving wind can be sufficiently drawn in, or it may not be possible to secure the air required for maintenance work on the gas tank, etc. necessary space
