Sensing electrode oxygen control in an oxygen sensor

Abstract:

An oxygen sensor comprises a housing defining an interior space, a sensing electrode, a reference electrode, a counter electrode, a separator retaining an electrolyte, and a chamber within the housing. The retained electrolyte provides ionically conductive pathways between each of the sensing electrode, the reference electrode, and the counter electrode within the housing, and the chamber contains the sensing electrode. The chamber comprises an opening, and the separator extends into the chamber and substantially fills the opening.
