Described are systems and methods of storing adsorbing diborane on carbon adsorption medium. The invention discloses a vessel for storing diborane. The vessel includes: a vessel interior; microporous carbon adsorbent in the vessel interior; diborane in the vessel interior at least partially adsorbed on the microporous adsorbent. The microporous adsorbent includes slit pores between graphite layers at a graphite layer spacing that increases an activation energy required for diborane degradation relative to an activation energy of degradation of non-adsorbed gaseous diborane at ambient pressure, and at the same temperature.

In order to separate diborane from a gas mixture containing diborane and hydrogen, the gas mixture is normally cooled in a storage tank using liquid nitrogen, wherein the diborane freezes out. In order to enable an extensively continuous separation of the diborane from the gas mixture, according to the invention, the gas mixture is brought into thermal contact with a liquefied gas in a heat exchanger, which liquefied gas is held at a pressure such that the diborane is liquefied by the thermal contact with the coolant, and the liquefied diborane is then discharged from the first heat exchanger and supplied to a storage tank. In a downstream, second heat exchanger, the diborane remaining in the gas mixture can then be caused to freeze out.
