Abstract

In a fuel cell vehicle, an occupant room is disposed at a front part of a vehicle body frame, and a rear side of the occupant room of the vehicle body frame is a load mount part. A hydrogen handling device is supported at least by the load mount part. The fuel cell vehicle includes a cover room that surrounds at least an upper part and a side part of the hydrogen handling device that is supported by the load mount part. A load room is disposed on the load mount part of the vehicle body frame. A discharge duct that discharges a hydrogen gas in the cover room upward from between the load room and the occupant room is connected to the cover room.

First claim

What is claimed is:

1 . A fuel cell vehicle in which an occupant room is disposed at a front part of a vehicle body frame, a rear side of the occupant room of the vehicle body frame is a load mount part, and a hydrogen handling device is supported at least by the load mount part, the fuel cell vehicle comprising:
a cover room that surrounds at least an upper part and a side part of the hydrogen handling device that is supported by the load mount part, wherein a load room is disposed on the load mount part of the vehicle body frame, and a discharge duct that discharges a hydrogen gas in the cover room upward from between the load room and the occupant room is connected to the cover room.

2 . The fuel cell vehicle according to claim 1 ,
wherein the discharge duct causes the hydrogen gas in the cover room to be discharged externally from a position higher than the load room.

3 . The fuel cell vehicle according to claim 1 ,
wherein a plurality of cover rooms are disposed as the cover room at a further front position than a rear wheel in a vehicle front-to-rear direction to be spaced from each other in the vehicle front-to-rear direction, a front cover room among the plurality of cover rooms and a rear cover room among the plurality of cover rooms are connected together via a connection pipe, the front cover room is connected to the discharge duct, and a hydrogen detection sensor that detects a hydrogen gas is provided on an upper part of the front cover room or the discharge duct.

4 . The fuel cell vehicle according to claim 3 ,
wherein at least two rear cover rooms are disposed as the rear cover room to be spaced from each other in a vehicle width direction, each of the rear cover rooms is connected to the front cover room via the connection pipe, and each connection pipe is inclined upward toward a vehicle front side.

5 . The fuel cell vehicle according to claim 2 ,
wherein a plurality of cover rooms are disposed as the cover room at a further front position than a rear wheel in a vehicle front-to-rear direction to be spaced from each other in the vehicle front-to-rear direction, a front cover room among the plurality of cover rooms and a rear cover room among the plurality of cover rooms are connected together via a connection pipe, the front cover room is connected to the discharge duct, and a hydrogen detection sensor that detects a hydrogen gas is provided on an upper part of the front cover room or the discharge duct.

6 . The fuel cell vehicle according to claim 5 ,
wherein at least two rear cover rooms are disposed as the rear cover room to be spaced from each other in a vehicle width direction, each of the rear cover rooms is connected to the front cover room via the connection pipe, and each connection pipe is inclined upward toward a vehicle front side.

7 . A fuel cell vehicle in which an occupant room is disposed at a front part of a vehicle body frame, a rear side of the occupant room of the vehicle body frame is a load mount part, and a hydrogen handling device is supported at least by the load mount part, the fuel cell vehicle comprising:
a cover room that surrounds at least an upper part and a side part of the hydrogen handling device that is supported by the load mount part, wherein a discharge duct that discharges a hydrogen gas in the cover room upward at a further vehicle rear side than the cover room is connected to the cover room that is arranged at a further vehicle rear side than a rear wheel, and a hydrogen detection sensor that detects a hydrogen gas is provided on the discharge duct at a further front position than a vehicle rear end of the load mount part.
