HYDROGEN ADSORBING MATERIAL FOR ADSORBING/DESORBING HYDROGEN AT LOW TEMPERATURE AND LOW-TEMPERATURE HYDROGEN STORAGE VESSEL

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen adsorbing material for adsorbing/desorbing hydrogen at low temperature, in which low-temperature hydrogen gas to be generated by vaporization of liquid hydrogen can be stored in relatively large quantities and from which the stored hydrogen can be desorbed easily and to provide a low-temperature hydrogen storage vessel using the hydrogen adsorbing material. SOLUTION: The hydrogen adsorbing material for adsorbing/desorbing hydrogen at low temperature contains h-BNH obtained by crushing h-BN (hexagonal boron nitride) mechanically in a hydrogen atmosphere. The low-temperature hydrogen storage vessel is formed by fixing the hydrogen adsorbing material for adsorbing/desorbing hydrogen at low temperature on the inner wall thereof.
