Gas sensor for determining the concentration of gas components in gas mixtures and use thereof |
摘要 |
A gas sensor for determining the concentration of gas components in gas mixtures is used in particular to measure the concentration of nitrogen oxides in exhaust gases of internal combustion engines or in the interiors of motor vehicles. It contains an electrochemical measuring cell which includes a first electrode situated on a solid electrolyte and an additional electrode. The electrode is made of an oxide material containing lanthanum which at least catalytically decomposes nitrogen oxides. The pump current flowing between the electrodes is used as a measure of the nitrogen oxide concentration in the gas mixture.
