Sorption properties and kinetic parameters of hydrogenating and dehydrogenating processes of Ti$_{0,475}$Zr$_{0,3}$Mn$_{0,225}$ eutectic alloy, in which partial substitution of each of its component with 2% and 5% of vanadium is performed, are investigated by Sieverts’ method. As determined, the introduction of vanadium within the specified limits results in decrease of the temperature of the start of intensive hydrogen absorption, decrease of the duration of hydrogenating process, and also in substantial increase of sorption capacity (up to 2.85% wt.). As shown, the alloys, which are subjected to the sorption—desorption cycling, possess as much activated surface that behave themselves with regard to hydrogen similar to intermetallic compounds and can absorb hydrogen at the room temperature and the pressure of 0.23 MPa from the first seconds of the contact of the specimen with the hydrogen-containing medium with the average rate of $(2—4) \cdot 10^{3}$ wt.%/s.
