The effect of Li incorporation into Pd on the hydrogen flow through a membrane Pd-electrode was found. It was of interest to determine the mechanism of this effect by a direct measurement of the diffusion coefficient of hydrogen in the Pd-H{sub x} phase and in the ternary Li-PdH{sub x} phase that was formed by the cathodic polarization of Pd in the solutions of lithium salts. A study of the effect of lithium on the diffusion of deuterium in the Li-PdD{sub x} phase might also be useful in solving this problem. In this work, a method of electrochemical extraction of absorbed hydrogen is used for these measurements; this method has been developed for nonsteady-state conditions, in particular. The X-ray examination of the formed phases was performed by a DRON-3M set-up with the use of CoK{sub {alpha}} radiation.
