Studies of electrode resistance in the electrochemical cell

Abstract

With thin metal films used as electrodes, double-layer processes can be tracked and identified by the complimentary technique of electrode resistance monitoring. This is demonstrated with chloride adsorption and lead underpotential deposition on gold electrodes. An example of the latter system with the process of controlled electrode emersion is included where the continuously measured resistance clearly shows that the lead adlayer is removed completely intact with the electrode. A simple model for adionic effects on conduction electron scattering at metal surfaces is proposed and found to correlate well with the experiment. The merits of the electrode resistance measurement for in situ studies are discussed. © 1983 Elsevier Sequoia S.A.
