Abstract

Four different contact methods have been utilized to study the electrode kinetics of high-Tc superconductor (HTSC)/solid electrolyte (SE) electrochemical systems. By using a transient technique, cell currents were measured versus time at a constant potential. Investigations with different electrochemical systems were implemented to calculate the potential-dependent charge transfer resistance of the electrochemical phase boundary reaction at the used solid electrolyte, the contact resistance and ohmic resistance of the solid electrolyte in contact with the HTSC. From the dc limis of the transient, a small increase in the electrode kinetic current is observed around Tc which must be correlated to the superconducting state of the HTSC. The results are interpreted as an enhancement of the electrode kinetics according to the values of the parameters mentioned before.
