A vehicle underbody structure includes a pair of rockers that are provided on both vehicle width direction sides of a vehicle underbody and extend in a vehicle front-rear direction, a battery that is disposed centrally in a vehicle width direction center between the pair of rockers and is disposed above a vehicle floor and on the lower side of a seat, a fuel tank that is disposed in the vehicle width direction center between the pair of rockers and is disposed under the vehicle floor and further toward a rear side of the vehicle than the battery, and a waste pipe that is coupled to a drive unit provided at a vehicle front side of the battery and extends in the vehicle front-rear direction between the battery and one of the rockers.

A fuel cell vehicle includes a travel prohibition control unit. In the case where a lid sensor detects an open state of a lid, the travel prohibition control unit performs travel prohibition control to prohibit travel of the fuel cell vehicle. In the case where the number of shift control operations has reached a release number within release time, the travel prohibition control unit releases the travel prohibition control, and in the case where the number of shift control operations has not reached the release number within the release time, the travel prohibition control unit continues the travel prohibition control. The release number is two or more.

A truck or tractor semi-trailer combination interconnected via a fifth wheel, comprising a cabin and an air collection chamber, the air collection chamber provided between a rear end of the cabin and the semi-trailer and having a front wall substantially adjacent or identical to a cabin rear wall, and a rear wall distanced and substantially coplanar to the front wall, which air collection chamber is provided with an air accession structure and a heat exchanger, the air accession structure providing air access to the air collection chamber and towards the heat exchanger, said heat exchanger provided in the rear wall of the air collection chamber extending at least partly over a width of the truck and wherein said air accession structure comprises air accession side ports provided on the side walls of the air collection chamber designed to provide at least a passive air flow from the air accession side ports towards the heat exchanger.

There is provided a high pressure container including a plurality of container bodies, each of the container bodies housing a fluid in a huh pressure state and being able to release the fluid through a release portion, (ii) opening section that is linked to the container bodies, and that opens at or above a predetermined opening temperature to release the fluid inside the container bodies, and (iii) a cover member that straddles the plurality of container bodies, that covers at least a portion of the plurality of container bodies, that is able to withstand a temperature of no less than the opening temperature, that is linked to the opening section, and that is capable of transmitting heat to the opening section.

A working machine includes a vehicle body; a traveling device that supports the vehicle body; a drive that drives the traveling device; and a cabin that accommodates an operator seat. The drive has a drive motor that drives the traveling device; a fuel cell that supplies electric power to the drive motor; a controller that controls power supply from the fuel cell to the drive motor; and a hydrogen tank that supplies a hydrogen gas for fuel to the fuel cell. The hydrogen tank is disposed in an upper portion of an internal space of the cabin.

A vehicle floor structure may include a floor disposed on a bottom portion of a vehicle body; a plurality of tank mounting members attached to a bottom surface of the floor; and a plurality of hydrogen tanks mounted on the plurality of tank mounting members, wherein each tank mounting member is aligned to extend in a longitudinal direction of the vehicle, the plurality of tank mounting members is spaced from each other in a width direction of the vehicle, each tank mounting member has a plurality of lower recessed portions provided in a lower portion thereof, and at least predetermined upper portions of the hydrogen tanks are received in the lower recessed portions of the tank mounting members, respectively.

A combined cooling and water braking system for a vehicle comprises a first water recirculation loop having a first heat exchanger configured to cool water flowing in the first water recirculation loop, the first water recirculation loop comprising a water conduit for transporting heat away from a propulsion device configured to generate a propulsion power for the vehicle. A second water recirculation loop having a second heat exchanger is configured to cool water flowing in the second water recirculation loop. A retarder is configured to be coupled to a pair of wheels of the vehicle. The second water recirculation loop may be selectively used for cooling the propulsion device and for providing water to the retarder for water braking. There is also provided a method for cooling a propulsion device of a vehicle and water braking a pair of wheels of a vehicle.

A pressure vessel assembly including a pressure vessel including a cylinder part and a first side part and a second side part, the first side part and the second side part each having a dome shape and being provided at two opposite ends of the cylinder part, nozzle members respectively provided on the first side part and the second side part, and a plurality of protectors connected to the nozzle members and configured to surround a respective outer surface of the first side part or the second side part.

A vehicle includes a vehicle body and a vehicle propulsion system. The vehicle propulsion system includes a fuel tank having a nozzle and a tank body. The tank body is made, at least in part, from carbon fiber materials. A method of producing a carbon fiber component for the vehicle is also described.
