Abstract

A combined gas sensor includes a first electrode and a second electrode, wherein the first and second electrodes are connected via an ion-conducting material. The first electrode is covered, in part, by a first catalytically active material. Further, a resistive gas sensor formed by a third electrode is arranged such that the third electrode is in direct contact with the first catalytic material and is not in direct contact with the first electrode.
