A high-voltage unit casing 10 for on-vehicle use to house therein a plurality of devices includes: a first side face 20; a second side face 21 opposed to the first side face; and a connecting portion 22 for structurally connecting the first side face and the second side face to each other. The connecting portion includes a partitioning portion 50 which is fixed to the first side face at a fixing portion and which extends from the fixing portion toward the second side face, the partitioning portion being located at a position separate from an upper surface and a lower surface of the high-voltage unit casing in an inner surface of the first side face. Spaces for placing at least one device included in the plurality of devices are formed on both upper and lower sides, respectively, of the partitioning portion.

An aircraft wing including: a wingbox; a fuel tank; a fuel cell system with a fuel cell; a fuel line configured to deliver fuel from the fuel tank to the fuel cell system; a propulsion system carried by the wingbox; and an electrical power line configured to deliver electrical power from the fuel cell system to the propulsion system. The fuel tank and the fuel cell system are located inside the wingbox, and the propulsion system is located outside the wingbox.

A motor vehicle has a pitch axis, a frame and a plurality of fuel cell stacks carried by the frame in respective fixed positions relative to the frame, wherein each of the fuel cell stacks comprises an outer casing and a plurality of fuel cells arranged in series within the outer casing, with the fuel cell stacks aligned along a rectilinear direction belonging to a plane orthogonal to the pitch axis.

Pickup trucks with an internal combustion engine (ICE), all electric, hybrid, plug in hybrid, must walk on loading flat bed, to load or unload, two stationary side walls, one-fold down tail gate, two taillights one on each side at the rear next to the fold down tail gate. With two full doors, with two full doors and with two smaller rear doors, or four full doors. It takes less compressed clean air to drive the DC alternators or DC generators from the compressed clean air engine. Also, the vehicle does drive 100% electric. A combination 100% electric and 100% compressed clean air system. No other vehicle has this kind of system.

A modular assembly for a fuel-cell vehicle is configured to connect to a bracket arranged along a longitudinal frame of the vehicle. The modular frame can include one or more components for powering the vehicle, including one or more of a fuel cell, a battery, a battery cooling system, and hydrogen storage tanks. The modular assembly can communicate with the fuel-cell vehicle through standard integration components regardless of the particular components in the modular assembly. The modular assembly can be readily removed from the fuel-cell vehicle and replaced with a different modular assembly containing different components.
