Abstract

We discuss the kinetics of electrochemical process on the high-T-c superconducting electrodes dependent on the type of superconductivity. The existence of the hump of an appreciable height in the temperature dependence of the current clearly points towards the BCS s-type superconductivity, involving a gap in the electronic spectrum. The height of the hump should be much less in the case of the unconventional d-wave pairing, while the absence of the hump is a signal about the importance of pair-breaking processes typical of the strong-coupling theories or even about bipolaron (bosonic) mechanism. Low-temperature tails at the current/temperature curve are also informative being determined by the electronic states within the gap typical of the unconventional d-wave pairing.
