% of its theoretical hydrogen production capacity after hydrolysis for 70min. Taking it for granted that the hydrolysis of MgH2, like any other solid-liquid reactions, should take place at the MgH2/H2O... of the 15h-milled MgH2, due to the complete exhaustion of the CaH2 constituent in the composite. According to Eqns.(3) and (4), the hydrogen production capacity of CaH2 is almost twice as much as that of Ca......

and LaNi5 are the main phases of all the alloys. The plateau pressure for hydrogen absorption/desorption decreases and the hydrogen storage capacity firstly increases and subsequently decreases... storage alloys have led to a new series of ternary alloys with a high hydrogen storage capacity[1-3]. Kohno et al[4] found that the maximum discharge capacity of the La0.7Mg0.3Ni2.8Co0.5 alloy......
to a decrease concerning the coefficient of performance of the system. By the substitution of Nd for Y, the hydrogen storage capacity increased, and the plateau pressure decreased a little, but the hydrogen absorption kinetics decreased dramatically. Cu addition can effectively improve the kinetics of hydride formation without changing the hydrogen storage capacity of La0.6Nd0.4Ni4.8Mn0.2. It has been......
