This Ph.D takes place on the hydrogen storage theme in metal hydride. In order to reduce the cost of the elements used for the preparation of hydridable materials, it is possible to use lower purity alloys as precursors. The compound selected belongs to the body centered cubic family consisting of Ti, V and Fe. This structure is known to store reversibly good quantities of hydrogen in conditions close to ambient. Thanks to modeling of the main parameters, it appears that the compound Ti15V71Fe14 presents interesting equilibrium pressure at room temperature. All properties of this reference material are measured by X-ray diffraction, EPMA, scanning electron microscopy and hydriding apparatus. A small amount of alloying elements has then been added individually then together in the composition of the reference material. Samples are analyzed and the results are compared to the referent. It appears that aluminum forms a solid solution of body centered cubic structure and improves the absorption capacity of the reference material. It is the same for silicon despite more complex behavior with the formation of several additional phases. In return the absorption kinetic of the material is reduced
