Abstract

A gas sensor for sensing the gas concentration in a measured gas mixture, particularly of a nitrogen compound, having a solid electrolyte which connects a first and a second electrode in an ion-conducting manner, the first electrode having a high activity with respect to oxidation or reduction of the gas component that is to be sensed, and the second electrode having a slight activity in this regard. The influence on the activity with regard to oxidation or reduction of the gas component to be determined, due to free oxygen present in the measured gas mixture, is approximately equally strongly pronounced at both electrodes.
