摘要：The gas sensor employs a reference gas channel which enables simultaneous orsequential pumping of oxygen and sensing of the exhaust gas (e.g., to determine if theexhaust gas is rich or lean). The method comprises: using a gas sensor comprising a firstelectrode and a reference electrode with an electrolyte disposed therebetween, whereinthe first electrode and reference electrode are in ionic communication, and a referencegas channel in fluid communication with the reference electrode and an exterior of thesensor; introducing an exhaust gas to the first electrode; applying a voltage to thereference electrode; ionizing oxygen at the first electrode; transferring the ionizedoxygen across the electrolyte to the reference electrode; forming molecular oxygen atthe reference electrode; ionizing the molecular oxygen on the reference electrode;transferring the ionized oxygen across the electrolyte to the first electrode to create avoltage; and measuring the voltage.
