抄録: The diffusivity of hydrogen in ordered and disordered states of Pd-12.5 at% Ce alloys was measured at room temperatures by an electrochemical permeation method. The ordered state has higher diffusivity and low activation energy for diffusion compared with those of the disordered state. The proposed models for the ordered state provide a good description of the experimental results of diffusivity in the alloy. The lower diffusivity of hydrogen in the disordered state can be explained in terms of the trapping effect at the lattice imperfections such as dislocations and the strain fields associated with the dissolved Ce atoms and/or Ce-Ce nearest neighbors.
