The mixed potential response for NO and NO 2 from two different oxide electrodes on yttria-stabilized zirconia (YSZ) was examined at 500 °C. The two electrodes were La 0.6Sr 0.4Fe 0.8Co 0.2O 3 (LSFCO) and Cr 2O 3. Sensors made with LSFCO electrodes had consistently lower sensitivity towards NO x as...
