“…Hydrogen permeability tests were performed in a temperature range 300e550 C by means of a conventional gas-permeation technique at a hydrogen pressure of up to 0.2 MPa. Prior to the hydrogen permeation experiments, a thin layer of w150 nm thick Pd coating was deposited on both sides of the ribbons by RF magnetron sputtering, so as to facilitate the dissociation and recombination of the H 2 molecules on the retentate and permeate sides, respectively [17].…”

“…Historically, Pd-based membranes dominate research and industrial practice for metal membranes applied to H 2 purification because they can naturally catalyze H 2 dissociation/recombination on the surface and have high H 2 permeability across a wide range of temperatures. − Pure Pd membranes have limitations, including being prone to H 2 -induced embrittlement below 300 °C and poisoning by S-containing species . To reduce the embrittlement problem and improve resistance to poisoning, Pd–Ag, Pd–Au, Pd–Cu, and other alloys have been investigated. − Experimental and theoretical methods have also been employed to develop and screen amorphous metal membranes. − The search for durable and cost-effective metal membranes with high H 2 permeability continues to be an active area . Among non-Pd metals considered as candidates for membranes, group 5 metals (V, Nb, and Ta) and related alloys have greater theoretical H 2 permeability than Pd.…”

To select useful surface coatings for high H 2 permeability metal membranes, the hydrogen transport properties in composite membranes of V, Nb, and Ta coated with different transition-metal carbides (TMCs) (TM = Ti, Hf, Zr) have been systematically investigated using first-principles calculations together with statistical mechanics methods. These calculations were used to predict the hydrogen flux and characterize the diffusion resistances in these composite materials. Our results indicate that the coating material on the permeate side controls the net H 2 flux at low temperature, where the H 2 desorption energies on the surfaces of the membrane coating are important. At sufficiently high temperature, H diffusion through the membranes controls the net flux. Overall, our results predict that TiC is the best coating and TiC/V/TiC is the best composite membranes among the materials studied.

“…In many experimental techniques, including electrolytic methods, hydrogen permeability through the membranes whose one or two surfaces are coated with a thin Pd film [3] is measured. It * E-mail: z.stepien@ajd.czest.pl is usually assumed that the presence of Pd layer does not affect hydrogen flow.…”

The vast majority of experimental techniques used for the measurements of hydrogen permeability through metallic membranes whose one or both surfaces are covered with a thin Pd film is based on the assumption that a ratio of film-to-membrane thickness is small enough to cause hydrogen flow to be independent of the Pd film thickness. In an attempt to verify this assumption, we have measured the hydrogen flow through the Pd 33 Ni 52 Si 15 amorphous membrane covered with Pd film of 10, 20, and 30 nm in thickness. Contrary to our expectations, we have found a dramatic decrease in hydrogen flow with the increase in Pd film thickness. Our findings are discussed in terms of potential barrier between the two different phases.
