Abstract
A supply device configured to supply hydrogen to at least one hydrogen system operating at an operating pressure, the supply device including at least one first tank configured to store hydrogen in a liquid state and at a pressure lower than the operating pressure, at least one main line connecting the first tank and the hydrogen system, at least one second tank configured to store hydrogen, in a liquid state and at a pressure higher than the operating pressure, supplying hydrogen to the main line, and at least one pressure regulation system situated in the second tank. An aircraft including at least one such supply device is also provided.
Claims10
A supply device configured to supply hydrogen to at least one hydrogen system operating at an operating pressure, said supply device comprising:
- at least one first tank configured to store hydrogen in a liquid state and at a pressure lower than the operating pressure, said first tank having at least one outlet orifice,
- at least one main line that extends from an upstream end connected to the outlet orifice of the first tank as far as at least one downstream end configured to be connected to a hydrogen system,
- at least one pump situated on the main line and configured to compress the hydrogen leaving the first tank to a pressure higher than or equal to the operating pressure,
- at least one main thermal regulation system situated upstream of the at least one downstream end of the main line,
- at least one second tank configured to store hydrogen in a liquid state and at a pressure higher than the operating pressure, said second tank supplying hydrogen to the main line between the pump and the main thermal regulation system, and
- at least one pressure regulation system situated in the second tank.
