Long-Range Diffusion of Hydrogen in Solid-Solution PdCe AHoys as Deduced from Absorption Experiments

摘要

The diffusion of H and the thermal decomposition of hydrides have been investigated at high temperatures in two PdCe alloys of composition 5% and 9% Ce. It has been found that the H diffusion coefficient obeys an Arrhenius-type of law with the following values of the activation energy W and diffusion constant Do.
