When porous electrodes are placed on both sides of zirconia ceramics, with one side exposed to the atmosphere and the other side to exhaust gas, an electromotive force is generated depending on the oxygen concentration in the exhaust gas.
This characteristic can be utilized for air-fuel ratio control of exhaust gas.
