Abstract
The galvanostatic dissolution of a parent metal Me in an electrochemical cell of the type Me/MeX/Me (MeX = cation-conducting
solid electrolyte) causes periodic oscillations of the anodic
overvoltage in a certain range of current density, pressure and
temperature. The amplitude of these oscillations is a function of the
applied mechanical pressure and their frequency depends on the electric
current density. In the present study the electrode kinetics of
transference cells of the type (+) Cu/AgBr/Ag (−) and (+) Cu/CuBr/Ag (−)
have been investigated by galvanostatic measurements and linear sweep
voltammetry, in order to obtain a better understanding of the nonlinear
kinetics. During anodic dissolution the anode surface develops a porous
structure which is correlated to the dislocation density of the anode.
Linear sweep voltammetry measurements suggest that the rate-limiting
step of anodic copper dissolution is the formation or the diffusion of
metal adatoms on the metal electrode surface. A qualitative model for
the influence of the processes on the oscillatory kinetics is proposed.
