Hydrogen storage alloy is expected as one of the promising storage system and it has the advantages that are higher safety and hydrogen storage density per volume than other storage systems. There are several kinds of the materials and the Mg based alloy is an attractive one for hydrogen storage one. Because of the density up to 7.6 wt.% in the reversible Mg hydride, the light weight and the reasonable price. In this research, they were prepared that the cold rolling Mg-foil, the Mg-foil deposited with Fe and Pd, and the Mg film deposited on a substrate and then deposited with Fe and Pd. Each hydrogenated films was examined with the X-ray diffraction (XRD) and the films which had formed hydride were carried out the differential scanning calorimetry (DSC) to characterize the hydrogen desorption temperature. From the results, we examined the thickness effect of Mg layer in hydrogen storage properties.
