Abstract
A reservoir safely accommodates a fuel using a barrier layer, which at least partly separates the contact areas of the reservoir and/or contact elements to be protected. The barrier layer is formed of a fire-proof medium which displaces volatile and ignitable fuel having a density less than the density of the fire-proof medium, providing a chemical-physical separation of hydrogen from the air surrounding the reservoir. In vehicles, particularly aircraft, safe operation may be improved by application of the barrier in the reservoir. In one embodiment, there is an additional reservoir filled with an inert material that surrounds the hydrogen reservoir.
Claims15
A reservoir for cryogenic fuel for use in applications where physical or chemical separation of the fuel from contact areas or contact elements to be protected is desired, the reservoir comprising:
- a sealably lockable storage volume for receiving the fuel;
- and
- a barrier fluid of a fire-proof medium having a density greater than the density of the fuel, wherein the fuel contained in the storage volume is separated, at least partially, from the contact areas or contact elements to be protected by a barrier layer formed of the barrier fluid.
