Sensor element for determining characteristic of gas in measuring gas chamber, particularly for determining portion of gas component, has two electrodes and solid electrolyte that connects electrodes

摘要

The sensor element (110) has two electrodes (116,118) and a solid electrolyte (120) that connects the electrodes. The former electrode is charged with gas over a measuring gas chamber (112), where a layer composition is provided. The former electrode is arranged in a planar layer (128), and the latter electrode is arranged in another planar layer (134), where the planar layers are different from each other. A reducing layer (146) is provided in third planar layer (147).
