Abstract

La présente invention concerne un détecteur électrochimique pour gaz comprenant un substrat d'électrolyte solide et une couche extérieure d'électrode poreuse en métal d'électrode qui lors de l'utilisation de l'élément détecteur est exposée aux gaz à analyser. Ce détecteur est caractérisé par la présence d'une couche poreuse intermédiaire d'une matière électrolyte au moins compatible liée intimement au substrat et à laquelle la couche extérieure d'électrode est à son tour intimement liée. Application à l'analyse de gaz tels que l'oxygène.
