Experimental data on hydrogen permeability through membrane alloys V₈₅Ni₁₅, V₉₀Ti₁₀, and V₉₀Co₁₀ (at %) are presented. Hydrogen permeability tests have been carried out in the temperature range of 623–873 K at pressures of ~4.5, 14, and 30 kPa. Results of X-ray diffraction analysis of samples are presented. Microstructure of the membrane alloys has been investigated before and after hydrogen permeability tests.
