Determination of permeability parameters of a Nb-based alloy intended for diffusion hydrogen purification
M.V. Stolbova

Non-Pd metal membranes are attracting increasing interest for hydrogen purification. Hydrogen permeability of Nb-TiNi (Nb_69Ti_15Ni_16,wt.%) alloy membrane has been investigated by the gas permeation technique. By pressurizing one side of the membrane with pure gas, the permeating flow rate through the membrane has been measured at various pressures and temperatures. For the proposed technique, we used a mathematical model of hydrogen transport taking into account diffusion and reversible capture by traps. The hydrogen-related parameters (diffusion coefficient, permeability and Sievert’s constant) of the Nb-TiNi alloy were evaluated.
