Abstract

L'invention concerne un détecteur électrochimique de gaz à électrolyte polymère solide, électrolyte se présentant sous la forme d'une membrane échangeuse de cations. Les électrodes de perception et de référence sont du même côté de la membrane. La contre-électrode est située de l'autre côté de cette dernière. Un pont bon conducteur des ions est créé entre les électrodes de référence et de perception par hydratation de la membrane, ce qui augmente la sensibilité du détecteur. Détecteur de CO, NO2 , alcool, etc. par exemple dans l'air.
