Abstract: An electrochemical permeation method has been used to determine the variation of the diffusivity of hydrogen through annealed and cold rolled Pd - Ni membranes as a function of temperature in the range 279 to 335 K and of Ni composition in the range 0 to 100 at. %. At a given temperature the hydrogen diffusivity decreases with an increase of Ni content in an almost logarithmic fashion, and at the same composition, the D values in the annealed samples are higher than those in the cold rolled samples. The experimental diffusivities have been discussed in terms of the proposed diffusion model with the lattice dilation effects.
