Title:
AMMONIA SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/182324
Kind Code:
A1
Abstract:
Provided is an ammonia sensor capable of improving detection responsiveness of an ammonia concentration. The ammonia sensor comprises: a plate-shaped sensor element in which a pair of electrodes (2) having different reactivities to ammonia are formed on a plate-shaped surface of a solid electrolyte (1) having oxygen ion conductivity; and a measurement device (12) for measuring at least one of a potential difference or a current between the pair of electrodes (2), wherein both of the pair of electrodes (2) are formed so as to be exposed to a gas to be measured (E); the solid electrolyte (1) is formed to be porous; and a plurality of gas flow holes, through which the gas to be measured (E) flows from one side of the solid electrolyte (1) of the plate-shaped sensor element (20) to the other side opposite to the one side, are formed, in the thickness direction of the plate-shaped sensor element (20).
