A marked retardation of the de-gassing of β-PdHx at 100C was detected experimentally. The role which was played by the critical deceleration of H diffusion near to the decomposition curve in the Pd-H system was analyzed theoretically. This deceleration was shown to make a possibly decisive contribution to the experimentally observed effect.
