Activated and prepared for operation alloy - hydrogen storage of AB5 type - (Mm0.2 Se7.5La9.3Ni83) was fused into ingots and activated. After a triple repetition of the activation, the measured circulating hydrogen capacity of the material was 1.62% wt. Designed test bench for certification of high pressure vessels. The carried out complex of tests showed that the hydrogen storage unit provides the parameters incorporated in the technical specifications, has sufficient reliability and has the possibility of its operation in laboratory conditions together with the fuel cell. A test bench was designed to certify high-pressure tanks, it allows to create internal pressure up to 55 MPa, with which high-pressure tanks were qualified, the passive safety system of which is provided with a safety membrane designed for a pressure not exceeding 18.5 MPa. Hydrogen storage on the basis of such an alloy can be recommended for production, compression and storage of hydrogen at facilities remote from power supply systems and require high-purity water.
