A fuel cell vehicle is a fuel cell vehicle configured to support a fuel tank including a cylindrical part extending in a longitudinal direction thereof, the fuel cell vehicle including vehicle body frames, and a tank frame. The vehicle body frames extend in the longitudinal direction between a front tire and a rear tire. The tank frame includes at least a fixing part fixed to the vehicle body frames, and a supporting part configured to support the fuel tank by extending in an outward and downward direction of the vehicle body frames, and coming into contact with the fuel tank below a lower end of the vehicle body frames and above a lowermost part of the cylindrical part.

A pressure vessel mounting system for mounting a pressure vessel to a vehicle chassis is disclosed. In various embodiments, the system includes a first end frame; a second end frame spaced a distance from the first end frame, the distance being sufficient to receive a pressure vessel between the first end frame and the second end frame; a first side frame extending between the first end frame and the second end frame, the first side frame configured for coupling to a first chassis rail of the vehicle chassis via at least one of the first end frame and the second end frame; and a second side frame extending between the first end frame and the second end frame. Via use of the pressure vessel mounting system, impact damage to pressure vessels may be reduced and/or eliminated.

A mounting system for mounting a tank to a space frame comprises a side mount configured to mount the tank to a center upper frame connection of the space frame, and a bottom mount configured to mount the tank to an elongate support member of the space frame. The bottom mount and the side mount are distinct mounts and configured to be mounted to the tank in a spaced apart relationship with respect to each other. The bottom mount and the side mount are coupled to a bottom and a rear side of the tank, respectively, and together are configured to mount the tank to the space frame.

A tank holding device is adapted to be mounted to a vehicle. The vehicle includes a mounting frame, a holding frame that is disposed on the mounting frame, and a tank that is disposed between the mounting frame and the holding frame. The tank holding device includes a positioning unit that is adapted to be connected to the holding frame and adapted for pushing the tank tightly against the mounting frame so as to secure the tank on the mounting frame.

This invention provides an adjustable bracket that can be used to attach auxiliary fuel tanks and other tanks to the bottom of a trailer or vehicle. The adjustable nature of the bracket allows it to be used on a variety of trailers, with different widths. The adjustable bracket comprises two parts with one sliding inside of the other. Each part has several slots that can be lined to create a bracket that is the ideal length to span the distance between the side panels of a trailer or vehicle. The bracket has holes in the bottom through which the bracket can be attached to a mounting retainer or strap that holds the tank in place.

A fuel system is provided that includes a fuel system frame and in some cases access steps. The frame can be mounted to a vehicle frame rail. Bracket assemblies can be coupled to the fuel system frame at a plurality of positions. The fuel tank can be mounted at neck portions thereof and can be supported on the frame rail between the neck portions, e.g., spaced a distance from the neck portions in a longitudinal direction of the fuel system. The access steps can be non-rectangular to provide a wide stepping portion even if the fuel system includes large tanks. The steps can be directly supported by an outside surface of the tank.
