Device for storing low-molecular gases under high pressure, particularly for storing fuel in vehicle formed as fuel cell vehicle, has inner shell and outer sheath surrounding inner shell

摘要

The device (5) has an inner shell (6) and an outer sheath (7) surrounding the inner shell. A gas (9) is arranged in the area provided between the inner shell and the outer sheath, whose molecular size is greater than that of the gas to be stored. The low-molecular gas is hydrogen, and the gas with the larger molecular size comprises nitrogen. The inner shell is formed of plastic.
