Title:
NOX SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/182323
Kind Code:
A1
Abstract:
Provided is a NOx sensor capable of improving detection responsiveness of a NOx concentration while simplifying a structure thereof. The NOx sensor comprises: a sensor element (20) having a pair of electrodes (2) formed on a surface of a solid electrolyte (1) having oxygen ion conductivity; a power supply device for supplying a voltage or a current between the pair of electrodes (2); and a measuring device for measuring one of a potential difference or a current between the pair of electrodes (2), wherein the solid electrolyte (1) is formed of a porous material so that both sides of the pair of electrodes (2) are exposed to a gas to be measured.
