Output Evaluation of Resistive Oxygen Sensor having Ce0.9Zr0.1O2 Sensing Material and Zr0.8Y0.2O2 -delta Temperature Compensating Material in Model Exhaust Gas

We fabricated resistive-type oxygen sensors having a Ce09Zr01O2 thick film as a sensing material and a Zr0.8Y0.202-delta thick film as a temperature compensating material for the first time, and measured the resistance of the two thick films and the output of the sensors in model exhaust gas which was a combustion gas of propane. Then, we considered whether the sensor could be used as a 'lambda sensor,' which can identify whether the airto-fuel ratio of exhaust gas is rich or lean region. As a result, we confirmed that the resistance of the Ce0.9Zr0.1O2 thick film was low and high in the case of rich and lean regions, respectively.
