Development and research of nanopores intermetallic
   hydrogen storages.

One of the integral components of all cycle of generating of the electric power with use of hydrogen is its accumulation in corresponding capacities directly for use in fuel cells. With reference to fuel cells for vehicles it means creation of compact capacities from materials which structure would allow to absorb operatively hydrogen in lots, to keep it at room temperatures and by doses to release it. Known materials for today do not possess necessary minimal capacity and have the raised temperature hydrogen desorption.

Listed above conditions define criteria of a choice of materials for capacities - they should possess the developed internal porosity with the greatest possible area of a surface. The material of which they will be made, should be steady in relation to oxides of carbon and the area of an internal surface should not change in the established temperature interval (<100^oC). In the best way to all these requirements satisfy with special image created composite intermetallic nanocrystalline structures possessing well developed nanopores ensemble. Nanopores in this ensemble must be connected each other by channel systems.  Presence of channels is an obligatory condition for downturn of temperature hydrogen desorption.

In the National Science Centre “Kharkov Institute of Physics & Technology” (Kharkov, Ukraine) carried out researches on nanopores structures creation. The certain results are received. It has been established, that ion beam-assisted deposition technology, which connects two processes – metals vapor deposition and  simultaneous bombardment by gas ions with energy some tens keV, can be used not only for creation of dense and wear protected  coatings, but also for formation of structures with the set level of internal porosity. These materials are stabile during the annealing at 500^оС. 

In the given direction there is an opportunity to create the breadboard models of fuel cells by association nanopores coatings with nanocrystalline and possessing good hydrogen permeation intermetallic materials.
