The hydriding and dehydriding reactions of M(NH2)y, where M=Li-x at.% Mg (x=0 -100 and y=1 -2), were examined for the purpose of developing reversible hydrogen storage materials. At the start of the reaction, the dehydriding temperatures of LiNH2 with partial Mg substitutions drastically decrease with an increase in the Mg concentrations, to approximately 370 K with x=30. Moreover, the reversible dehydriding and rehydriding reactions of Mg(NH2)2, in which 9.1 mass% of hydrogen can be stored, were successively investigated. The reversible hydriding and dehydriding reactions of M(NH2)y are useful for the development of hydrogen storage materials for fuel cell applications.
