摘要

Results of electrical resistance measurements are given on Pd,, Ag,, alloy during hydrogen uptake from gaseous Il, atmosphere and from liquid electrolyte by cathodic charging. For both cases in the course of a monotonous increase of the hydrogen concentration in the alloy, the electrical resistivity shows anomalous behavior. These kinetic curves reflect the effect of phase changes in the non-equilibrium state. The 'non-equilibrium' expression is used in this entire work in the sense that no care was taken in waiting for the stable value of resistivity after any partial filling, but the resistivity was frequently measured while the sample was continuously charged with hydrogen. A model has been proposed for the interpretation of the experimental findings. (C) 2000 Elsevier Science BN. All rights reserved. [References: 9]
