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,

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,

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.

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 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.

4. 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 plurality of cover rooms which surround at least an upper part and a side part of the hydrogen handling device that is supported by the load mount part,

wherein a first discharge duct that discharges a hydrogen gas in a first cover room among the plurality of cover rooms upward at a further vehicle rear side than the first cover room is connected to the first cover room that is arranged at a further vehicle rear side than a rear wheel,

a first hydrogen detection sensor that detects a hydrogen gas is provided on the first discharge duct at a further front position than a vehicle rear end of the load mount part,

a second cover room and a third cover room among the plurality of cover rooms are disposed 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,

the second cover room arranged on a front side and the third cover room arranged on a rear side are connected together via a connection pipe,

the second cover room on the front side is connected to a second discharge duct that discharges a hydrogen gas in the second cover room upward from between the occupant room and a load room that is disposed on the load mount part, and

a second hydrogen detection sensor that detects a hydrogen gas is provided on the second discharge duct or an upper part of the second cover room on the front side.
