Abstract
Solid electrolyte sensors (SES) based on yttria-stabilized zirconia (YSZ) can exhibit improved selectivity to redox active gases when they are operated with dynamic electrochemical methods like cyclic voltammetry (CV) or impedance spectroscopy (IS). To clarify basic electrochemical processes at the measuring electrode, experiments in the temperature range 650
