Measuring cell for determining oxygen concentrations in a gas mixture having a partition consisting of an electrolyte material such as ZrO2, which reversibly reacts with oxygen and is ion conductive. The measuring cell is characterized in that the partition closes a hollow body and projects therefrom so that the electrodes may be provided on the same side to reduce disturbing influences on the measurement.

A cell for measuring the ratio between oxygen concentrations of two gas mixtures, comprising: a hollow body for communicating one of the gas mixtures to an opening therein; a flat partition sheet closing said opening and projecting therebeyond so that a first area of one side of said sheet is expose

A cell for measuring the ratio between oxygen concentrations of two gas mixtures, comprising: a hollow body for communicating one of the gas mixtures to an opening therein; a flat partition sheet closing said opening and projecting therebeyond so that a first area of one side of said sheet is exposed to the gas mixture inside said hollow body while outside of said hollow body a second area of said one side may be simultaneously exposed to another gas mixture, said flat sheet being electrolyte material which reversibly reacts with oxygen and is ion conductive; electrically separate gas permeable electrodes on said first and second areas respectively; and means for electrically contacting said electrodes to measure the voltage therebetween as a measure of the ratio between the oxygen concentrations to which said electrodes are exposed.
