In this processes for hydrogen production from fossil fuels, separation and purification is a critical technology. (Ni60-Nb40)95-Pd5 alloy ingots were prepared by arc-melting the mixture of pure metals in an Ar atmosphere. Melt-spun ribbons were produced by the single-roller melt-spinning technique in an Ar atmosphere. Amorphous structure and thermal behavior were characterized by XRD and DSC. The permeability of the (Ni60-Nb40)95-Pd5 amorphous alloy membrane was characterized by hydrogen permeation experiments in the temperature range 623 to 773 K and pressure of 2 bars. The maximum hydrogen permeability was 3.54？10-9[mol？m-1 s-1？pa-1/2] at 773 K for the (Ni60-Nb40)95-Pd5 amorphous alloy.
