The total conductivities of a series of electrolytes have been determined over a wide range of oxygen activity in atmospheres of mixtures. At 1200° and 1400°C and low oxygen activities, a significant conductivity contribution corresponding to hydrogen ion (proton) conduction was found for electrolytes with high dopant contents. The experiments are interpreted in terms of a defect model involving two dopants.
