A high pressure canister unit includes: plural arrayed canister bodies, each canister body being formed in a circular cylinder shape, and including an opening at at least one end portion in its axial direction; a coupling member that is connected to the opening of each of the canister bodies and that couples the plural canister bodies together, and the coupling member including a flow path placing interiors of the canister bodies in communication with each other; a box-shaped case that is configured to house the plural canister bodies and the coupling member, the case including a through hole; and a leader tube that is provided to the coupling member, that leads out to an exterior of the case through the through hole of the case, and to which a valve capable of opening and closing the flow path is attached.

A vehicle lower portion structure includes a pair of rocker panels and an electric power supply device. The rocker panel is configured to include an outer portion, an inner portion, and a first shock absorbing portion. The outer portion is positioned on an outer side in a vehicle width direction. The inner portion is formed integrally with the outer portion, is positioned inward of the outer portion in the vehicle width direction, and forms a closed sectional portion with the outer portion. The first shock absorbing portion extends in the vehicle width direction from the outer portion to the inner portion in the closed sectional portion and is disposed to overlap the electric power supply device in vehicle side view.

A vehicle includes a motor, a power converter, a fuel tank, and a three-phase line. The motor moves the vehicle. The power converter is connected to the motor. The power converter is configured to convert electric power and to supply the converted electric power to the motor. The fuel tank is disposed between the motor and the power converter. The fuel tank has a tank bottom on a side of a bottom of the vehicle. The tank bottom has a recess. The three-phase line is provided in the recess. The motor is electrically connected to the power converter via the three-phase line.

A cylindrical hydrogen tank is housed under a floor tunnel, which is disposed at the center in a vehicle width direction of a floor panel along a vehicle front-back direction so as to protrude upward along a height direction, and includes a casing having a load bearing property. A seat cross member is disposed on a side of the hydrogen tank along the vehicle width direction. A seat pipe is joined to the seat cross member and disposed so as to extend along the vehicle width direction. The seat pipe and the seat cross member are arranged within the height of the hydrogen tank in a vehicle height direction, and also respectively located above and below the most outwardly protruded lateral end point in the vehicle width direction of the hydrogen tank.

A heavy-duty truck chassis has a frame assembly having a first rail spaced from a second rail to define a gap therebetween. A front axle is supported by the frame assembly and is positioned proximate a front portion of the frame assembly. A rear axle is supported by the frame assembly and is positioned proximate a rear portion of the frame assembly. A fuel tank is supported by the frame assembly and positioned in the gap and behind the rear axle.

A vehicle lower portion structure has an internal combustion engine that is disposed on one side in a vehicle width direction in a power unit compartment, an inverter that is disposed on another side in the vehicle width direction in the power unit compartment, an exhaust pipe that extends in a vehicle front-rear direction through a dash panel separating the power unit compartment from a vehicle cabin, and is disposed within a floor tunnel that is provided in a central portion in the vehicle width direction at least at a position of the dash panel, and whose one end portion is connected to the internal combustion engine, a battery that is provided on a vehicle rear side of the dash panel, high-voltage power cables that extend in the vehicle front-rear direction on another side in the vehicle width direction and connect the inverter and the battery together.

A frame arrangement for a vehicle may include first and second longitudinally extending side members that each have an upper portion and a lower portion. The upper portions are spaced laterally apart by a first distance, and the lower portions are spaced laterally apart by a second distance less than the first distance. The frame arrangement may further include at least one storage tank or battery positioned between the side members.

A shielding device of a passenger compartment of a motor vehicle for shielding an interior of the passenger compartment from a hydrogen tank in the motor vehicle includes a basic body. The basic body has a fiber-reinforced composite material with a hydrogen-permeation-inhibiting coating. The basic body is constructed as a wall or wall segment of the passenger compartment.

A fuel cell vehicle includes tanks configured to store a fuel gas to be supplied to the fuel cell, the tanks being respectively disposed in front of and behind the motor drive unit such that a longitudinal direction of each of the tanks corresponds to a width direction of the fuel cell vehicle. The tanks are disposed such that respective end portions of the tanks on a side on which the high-voltage wiring portion is positioned are outside the high-voltage wiring portion in the width direction of the fuel cell vehicle and the respective end portions of tanks overlap a tire-wheel assembly in a front-rear direction of the fuel cell vehicle.
