Abstract

A fuel cell vehicle includes a fuel tank module that accommodates a fuel gas, and a rail arranged along a vehicle-width direction of the fuel cell vehicle in a floor part of the fuel cell vehicle, in which the fuel tank module includes a casing that accommodates a fuel tank accommodating the fuel gas, a block unit arranged in a bottom surface of the casing and configured to be attachable to and detachable from the rail and movable along the rail, and a fixation unit that can fix the block unit to the rail and release fixation of the block unit to the rail.

First claim

What is claimed is:

1. A fuel cell vehicle comprising:
a fuel tank module that accommodates a fuel gas; and
a rail arranged along a vehicle-width direction of the fuel cell vehicle in a floor of the fuel cell vehicle,
wherein the fuel tank module includes:
a casing that accommodates a fuel tank accommodating the fuel gas;
a block unit arranged in a bottom surface of the casing and configured to be attachable to and detachable from the rail and movable along the rail; and
a fixation unit that is configured to fix the block unit to the rail and release fixation of the block unit to the rail.

2. The fuel cell vehicle according to claim 1 ,
further comprising a duct communicating a space accommodating the fuel tank and an outside of the fuel cell vehicle,
wherein the fuel tank includes a safety valve that opens when temperature becomes greater than a predetermined temperature, and the fuel tank is configured such that a direction in which the fuel gas in the fuel tank is discharged via the safety valve when the safety valve opens is a direction of the duct with respect to the safety valve.

3. The fuel cell vehicle according to claim 2 ,
wherein the fuel tank module includes a regulation guide that is provided in an upper side of the safety valve in a vertical direction, and is parallel to the floor part.

4. The fuel cell vehicle according to claim 1 ,
further comprising a guide provided in the floor,
wherein the fuel tank module has a receiver that fits to the guide when the fuel tank module is mounted to the fuel cell vehicle, and
the guide and the receiver are arranged such that the guide and the receiver contact each other before the rail and the block unit contact each other when the fuel tank module is mounted to the fuel cell vehicle.

5. The fuel cell vehicle according to claim 4 ,
wherein the guide includes an end portion on a side which the receiver approaches when the fuel tank module is mounted to the fuel cell vehicle, wherein the end portion is provided in a convex shape.
