ABSTRACT:
An oxygen sensor and a method for manufacturing the oxygen sensor are provided. The oxygen sensor includes a zirconia layer having first and second sides. The second side is opposite the first side. The oxygen sensor further includes a first electrode disposed on the first side of the zirconia layer. The oxygen sensor further includes a second electrode disposed on the second side of the zirconia layer. The oxygen sensor further includes a porous channel structure configured to route air therethrough to the first electrode while preventing hydrocarbons from flowing therethrough and contacting the first electrode, such that a signal between the first and second electrodes is indicative of an amount of oxygen in exhaust gases contacting the second electrode.
