Abstract

First investigations revealed that solid electrolyte sensors based on yttria-stabilized zirconia can exhibit improved selectivity to redox active gases when they are operated with dynamic electrochemical methods like cyclic voltammetry or pulsed polarization. To clarify basic electrochemical processes at the gas electrode, extensive investigations in non-equilibrated gas mixtures containing hydrogen, carbon monoxide and propene have been carried out by using cyclic polarization methods. The results show that it is possible to distinguish between different species in a mixture by using sensors which are non-selective when operated with static electrochemical methods.
