摘要:
An apparatus for storing gases such as hydrogen gas at cryogenic temperatures. The hydrogen gas is stored in a storage vessel 1 at cryogenic temperatures and those cryogenic temperatures are sustained by a heat exchanger (comprising a reservoir 10, a fluid connection means 12, a coil supply tube 14 and coils 16) which provides nearly uniform distribution of a volatile liquid throughout the hydrogen gas being stored. The storage vessel contains an adsorbent of the physiosorption kind. The self regulating flow of oxygen through the heat exchanger maintains the adsorbent at a suitable cryogenic storage temperature even when the apparatus is not being used to supply hydrogen.
