AI Technical Summary
Technical Problem
Hydrogen tanks in motor vehicles made of deformable materials experience changes in volume and shape due to pressure fluctuations during filling and discharging, necessitating rigid constraints to the duct, which complicates design and flexibility.
Method used
A hydrogen tank system using a deformable casing with tie rods and a containment element made of elastically flexible material, allowing the tank to expand and contract while maintaining connection to the duct, ensuring stability and flexibility.
Benefits of technology
Enables the use of tanks with alternative shapes, enhancing design freedom and maintaining structural integrity during pressure changes, facilitating efficient hydrogen flow and tank constraint.

Abstract
To provide an automobile that can meet the requirements described in the background technology. [Solution] A hydrogen-powered vehicle (1) is described, comprising a tank (15) designed to be filled with hydrogen, a frame (10) designed to support the tank (15), and a valve (17) fixed to the frame (10) and designed to selectively allow the tank (15) to be filled with hydrogen and to be emptied of hydrogen, wherein the tank (15) comprises a first part (20) fixed to the valve (17), a second part (21) that can be freely deformed as a result of fluctuations in the internal pressure of the tank (15), and a third part (22), and the vehicle (1) further comprises a housing element (32) interposed between the third part (22) of the tank (15) and the frame (10).
