In the prior and later period of hydrogen absorption the rate-controlling steps are the chemical reaction and the hydrogen diffusion in the hydride phase in ML-Ni-Co-Mn-Al alloy respectively. Adding Cu, the mechanism of hydrogen absorption changes from chemical reaction to the nucleation and growth of β-phase in the prior period, and the process of hydrogen absorption is still controlled by the diffusion in the later period.
