Apparatus

An aircraft propulsion arrangement, comprising a cryogenic source 210, comprising a cryogenic resource, such as liquid hydrogen, which is used to provide a heat exchanger function in a heat exchanger 222, 224, and is then used to function as a fuel for a fuel cell 230. In some embodiments, there is...

Beschreibung
Zusammenfassung:	An aircraft propulsion arrangement, comprising a cryogenic source 210, comprising a cryogenic resource, such as liquid hydrogen, which is used to provide a heat exchanger function in a heat exchanger 222, 224, and is then used to function as a fuel for a fuel cell 230. In some embodiments, there is a first, passive heat exchanger 222, comprising a second cryogenic resource, and a second, active heat exchanger 224. The second cryogenic resource may be an inert fluid, with a boiling point lower than that of the first cryogenic resource, such as helium.
