The materials obtained have a high defectiveness, are nanostructured, demonstrate increased hydrogen sorption characteristics (hydrogen capacity from 6.75 to 5.5% by weight), have significant improved kinetics of hydrogen desorption by 5-7 times compared to MgH2 hydride phases without alloying items. A laboratory metal hydride air cell has been created, which allows conducting research as an air, as well as an MN electrode, using a 3-electrode polarization circuit. It is possible to pre-charge the hydride electrode with its subsequent discharge in a pair with an air electrode. The performance characteristics of the developed composite materials on the basis of MgH2 ensure their rational use in stationary conditions, in systems of autonomous power supply, in combination with high-temperature solid oxide fuel cells.
