Abstract
Cellule de mesure comprenant un électrolyte solide conducteur des ions oxygène et recouvert d'une première couche servant d'électrode de mesure et d'une seconde couche servant d'électrode de référence, au moins la première couche étant revêtue d'une troisième couche poreuse ayant une activité catalytique. Au moins la troisième couche 18 contient une matière à forte pression partielle d'oxygène pour conférer à la cellule une courbe caractéristique à faible pente en particulier dans la plage du rapport de mélange air/carburant, c'est-à-dire du facteur lambda environ égal à 1, cette couche contenant une matière à pression partielle moyenne d'oxygène pour conférer à la cellule une caractéristique à pente moyenne et une matière à faible pression partielle d'oxygène pour obtenir une caractéristique à forte pente. Application à la détermination de la teneur en oxygène de gaz, en particulier des gaz d'échappement de moteurs à combustion interne ou des gaz de carneau de foyers.
