A fuel cell vehicle comprising: a hydrogen tank which is mounted on the vehicle so as to have a center axis generally parallel to a front/rear direction of the vehicle; a high-voltage electric component which is positioned either forward or rearward of the hydrogen tank and which operates on high voltage; an aftercooler placed between the hydrogen tank and the high-voltage electric component to cool compressed air; and a fuel cell stack which is supplied with the cooled compressed air.

A mounting assembly for a vehicle is provided. The vehicle has a chassis with a first frame rail and a second frame rail extending longitudinally. The mounting assembly has a bracket with a concave region to receive and attach to a compressed gas tank to move the compressed gas tank away from an external force applied to an outer surface of the tank and in a first direction towards and beneath the first frame rail. The bracket has a first end region connected to the first frame rail to position the tank on an outboard side of the first frame rail.

A high-pressure vessel mounting structure includes: a plurality of high-pressure vessels arranged on the upper surface of a bottom wall in a front-rear direction of a vehicle body with a vehicle width direction as an axial direction; a plurality of load transmission members each provided between the high-pressure vessels on the bottom wall and extending along the axial direction; a connection member that connects one axial end of each of the high-pressure vessels; and a support member that supports the other axial end of each of the high-pressure vessels, and the support member can move relatively inward in the vehicle width direction with respect to the high-pressure vessel when a load is input from outside in the vehicle width direction.

Methods and systems for an electric vehicle (EV) propulsion are provided. A method for operating an EV propulsion system is provided, in one example, that includes, while a traction battery assembly generates electric power, initiating start-up of a hydrogen fuel cell assembly based on a first battery state of charge (SOC) threshold and a first hydrogen fuel storage threshold to transition into a hybrid mode of operation. In the propulsion system, the traction battery assembly includes one or more traction batteries that are electrically coupled to one or more hydrogen fuel cells in the hydrogen fuel cell assembly via a distribution assembly, where the distribution assembly is electrically coupled to a traction motor.

A hydrogen fuel tank mounting system for a vehicle comprises a first mount for mounting a first portion of the fuel tank in a fixed position and a second mount for slidably mounting a second portion of the fuel tank. In this manner, the mounting system reduces stress on fuel system components when accommodating expansion and contraction of the hydrogen fuel tank, improving durability. The fuel tank may be a dual port fuel tank, and the first and second portions may be elongated neck portions. The fixed mount may be a bracket formed in two portions with a clearance between them. A sleeve may extend through at least part of the portions of the brackets to distribute shear forces away from an interface between those portions. The provision of a slidable mounting also allows pre-assembly of the fuel tank and mounts, facilitating installation of the hydrogen fuel system.

A support system is provided for a vehicle. The support system can include one or more bracket assemblies in which each includes a coupling member and a curved member in which the coupling member is affixed to a structure of the vehicle. A housing can be supported by the one or more bracket assemblies in which the housing encloses a container that stores a material such that the housing protects the container and the material. The support system provides movement between a length of the container so as to reduce deterioration of the support system.
