Abstract
The lowest limit of operation temperature for ceria-based solid electrolyte oxygen sensor was significantly reduced with a use of perovskite-type oxide electrodes. In particular, the sensor with La0.6Sr0.4Co0.98Ni0.02O3 exhibited theoretical emf even at 200 °C. The cathodic overpotential, which was measured by current interruption method, was low for an electrode operative at low temperatures.Keywords
