Equilibrium pressure of sorption and desorption have been measured over vanadium hydride of the composition VX0,8-2,0 where X is H2, D2 or their mixture. The work has been done using electrolytic vanadium VEL — 2. Temperature dependencies of desorption equilibrium pressures for vanadium hydride VX1,0-1,9 in a pressure range 1 — 550 bar were found to be : 1g P(atm.) = -2085/T + 7,5 and 1g P(atm.) = -2454/T + 8,2 for protium and deuterium, respectively. Temperature dependence of pressure, obtained for mixtures H2 and D2, are between those found for pure D2 and H2 but shifted toward dependence for D2. Based on the found dependencies, the enthalpy of relevant vanadium dihydride phases generation was calculated.
