Pd and its binary and ternary alloys with other noble metals (Pt, Rh, Au) were deposited on a gold substrate by electroplating from aq. solns. to produce limited vol. thin-layer electrodes and electrochem. tested by cyclic chronovoltamperometry and chronoamperometry in respect to the reversible H electrode. The electrochemical H absorption in the electrodes depended on the composition of electrode material and on the electrode potential. The addn. of alloying metals resulted in a decrease in the absorption capacity of Pd except for Rh where an increase in the absorption capacity was observed. A hysteresis was observed in chronoamperometric absorption/desorption expts. The hysteresis was higher for pure Pd than for its alloys. The alpha-beta phase transition rate in the electrode material influenced the kinetics of H absorption/desorption.
