As a reference, similar measurements were taken on pure palladium. While hydrogen diffusivity for the amorphous structures was smaller than that for a palladium membrane, the amorphous membranes exhibited higher hydrogen solubility, resulting in comparable hydrogen permeability. An increase in zirconium content increased permeability by enhancing hydrogen diffusivity, although the amount of hydrogen contributing to the hydrogen flux was not affected. (C) 2013 Elsevier B.V.
