Abstract
In general, an electrode is a system made up of an electronic (metal) or mixed (MIEC) conductor in contact with a solid electrolyte and is host to one or several oxidation-reduction reactions. The electric response of an electrode is described in terms of its polarization and of the current density crossing its interface. These parameters are measured by using several techniques, mainly complex impedance spectroscopy. Experimental results are interpreted in terms of charge transfer and ion diffusion, and the exercises allow the reader to study several electrodes, such as Pt,O2/YSZ; H2,Ni/YSZ; and H2O,M/YSZ (M = Pt, Ni).
