popup.description2
It was found that the addition of Ni, Ti, Fe and Y to magnesium allows to obtain a hydrogen capacity of 6.0 wt. %, while the kinetics of hydrogen release from the hydride phases of nanocomposite alloys is enhanced by 5, 6 and 15 times compared to pure MgH2. This provides a possibility of their practical use as hydrogen storage materials in stationary applications.
The obtained La3Ni9.7Mn0.5Al0.3Сох (x = 0; 0.7 and 1.9) alloys with AB3.5-4.15 stoichiometry form stable hydrides and demonstrate high efficiency. A reversible MH-air cell was created, which can be charged under the action of sunlight (accumulating hydrogen in the form of metal hydride) and discharged by reduction of oxygen in the air. It can be used to generate electricity.
