β¦ Synopsis
The effects of iron addition on the hydriding properties of Mg 6 Pd were investigated. It was found that 15 min of co-milling Mg 6 Pd and Fe in a high energy mill was sufficient to improve the sorption kinetics. Rietveld refinement of neutron powder diffraction patterns indicated that the presence of iron drastically modifies the system's micro-structure.
A possible link between structure and hydrogen storage properties is discussed.

Magnesium hydride is a very attractive material for solid state hydrogen storage due to their high mass and volume capacity, but its slow absortion/desortion kinetics does not favours its practical use in mobile applications. Recently it has been observed that the addition of small quantities of tra
Hydrogen is considered a good energy carrier candidate for future automotive applications that could be part of a carbon-free cycle. Metal hydrides are often preferred over pressurized gas and other hydrogen storage methods because of their gravimetric and volumetric storage capacities and safe oper
Effect of stoichiometric ratio on the electrochemical properties of negative electrodes was investigated for alloys with composition Mm(Ni,,,Mno.4Al,,,Co~,,), (Mm = misch metal, 0.88 < x < 1.12). The discharge capacity at a current density of 0.2Ag-' increased with an increase in unit cell volume of
Two kinds of kinetic models, which are Jander model and Chou model, were applied to investigate the hydriding kinetic behavior of MgeNi based alloys. By comparing the calculated values with experimental data, it can be seen that both models were successfully used in the diffusion-controlled hydrogen
