Abstract

Amperometric hydrocarbon sensor based on the oxygen pumping current was studied for monitoring hydrocarbon in exhaust gas. It was found that the oxygen pumping current through the sensor using La_0.9Sr₂0.1Ga_0.8Mg_0.2O₃ electrolyte at 1 V application monotonically increased with C₃H₆ concentration, but hardly depends on oxygen concentration when Pt and SnO₂ were used for the active and the inactive electrode for oxidation, respectively. The oxygen pumping current of the developed sensor under 1 V application is hardly changed by coexisting CO and H₂O. Consequently, the developed amperometric hydrocarbon sensor can detect hydrocarbon with high selectivity.
