Abstract

One of the alternative and topical ways of intermetallic and nonferrous materials application is a metal hydrides formation. Metal hydrides allow storage of hydrogen; carry out gas purification and compression.Development of powder metallurgy provides new possibility for investigations in the field of alternative way of hydrogen storage. Solid form of hydrogen storage with the possibility of reversible sorption, gives opportunity for creation autonomous energy storage systems and use hydrogen like a modern energy carrier.Lanthanum-nickel based alloys allow hydrogen storing at ambient temperatures and pressure not higher than 15 bar, which makes the application of these alloys quite practical. The disadvantages of these alloys are the high cost of the initial powdered pure metals and the relatively low mass content of hydrogen in the final alloy. Despite this, La-NI alloys are quite interesting and prospects for further study and modifications.
