Abstract

Abstract

Limiting current oxygen sensors with LSCo as dense diffusion barrier and Yttria (8% in molar fraction) Stabilized Zirconia (YSZ) as oxygen ion conduction solid electrolytes was developed through an effective technology. This type of sensor can get stable current plateau in whole range of air-fuel ratio. Compared with existing limiting current oxygen sensors, it has a simpler design, a faster response and lower cost, thus has a good application.
