The invention relates to a reference electrode for electrolytic cells having an ion-conducting solid electrolyte, to sensors comprising the reference electrode of the invention and to their use of the reference electrode for analyzing gases.

Reference electrode for electrolytic cells having an ion-conducting

A solid electrolyte sensor device for determining gas concentrations in measurement gases, with a sensor formed by a solid electrolyte which is arranged between at least two electrodes. The electrodes are permeable to gas and at least one of the electrodes faces the measurement gas. An electrical device is also provided for detecting and processing concentration-dependent sensor output values. For the purpose of permanently preventing disruptive adsorption of measurement gas components on the sensor or on the corresponding sensor electrode, an adjustable oxygen source is arranged in the vicinity of the sensor electrode which faces the measurement gas so that oxygen or oxygen radicals can be introduced into the measurement gas via this oxygen source for the oxidation of the measurement gas.
