ABSTRACT:
A sensor comprises: a pump cell comprising an inner pump electrode, an outer pump electrode, a pump cell electrolyte layer interposed between the inner pump electrode and the outer pump electrode and a cell isolation layer disposed on the inner pump electrode on a side opposite the pump cell electrolyte, wherein the outer electrode is in fluid communication with a reducing gas. A reference cell is in operable communication with the pump cell, the reference cell comprising an outer reference electrode and an inner reference electrode, and a reference cell electrolyte interposed between the outer reference electrode and the inner reference electrode. A diffusion limiting material flanks both sides of a chamber formed between the cell isolation layer and a cell separation layer, wherein the cell separation layer comprises a via coaxial and in fluid communication with the inner pump electrode, the diffusing limiting material, and the outer reference electrode, and wherein the diffusion limiting material has a gas permeability such that the limiting current of oxygen in air is about 0.05 mA to about 5 mA per cm2of pump electrode area.
