the considered composite–hydrogen system: the tem-
perature-dependent value of the equilibrium hydrogen
pressure P0 in the system. For diffusion-controlled
dehydrogenation with the investigated material
(Fig. 2a, curve 3), it was proposed in [17] that the fol-
lowing expression be used for p(T): p = T(1 –
(P/P0)1/2). Introducing this correction for our k values

yields Ea = 124 1 kJ (mol H2)–1, which is consistent
with the data of other works (e.g., [19–22]) where sim-
ilar systems were examined: the energy of dehydroge-
nation activation is 121.3 kJ (mol H2)−1 for MgH2 +
10% NiCl2 (compared to 160 kJ (mol H2)−1 for the
dehydrogenation of pure MgH2 [18]).

Adding GLM, and especially Ni/GLM, greatly
increases the rates of hydrogen sorption and desorp-
tion in magnesium composites. The dehydrogenation
reaction rate constant grows by 1.4 and 2.3 times for
Mg + GLM and Mg + Ni/GLM, respectively, com-
pared to that of Mg without additives. The hydrogena-
tion rate constant for composites with Ni/GLM addi-
tives is 15–37 times higher than the one for the sample
without additives. For all processes, the effect of addi-
tives is also expressed as a substantial reduction in the
Avrami factor, testifying to the geometric constraint
on the regions of nucleation (with the rate of this pro-
cess growing) and the contribution from H atom diffu-
sion becoming the limiting step. Adding Ni/GLM
improves the cyclic stability as well. It provides rapid
and almost complete repeated hydrogenation for at
least ten cycles. During cycling, the contribution from
the slow process to the kinetics of hydrogen sorption
diminishes without reducing the hydrogen capacity of
the composite.
