Title:
ELECTRODE FOR LIMITING CURRENT TYPE GAS SENSORS, METHOD FOR PRODUCING SAME, LIMITING CURRENT TYPE GAS SENSOR, METHOD FOR MANUFACTURING LIMITING CURRENT TYPE GAS SENSOR, AND SENSOR NETWORK SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/098372
Kind Code:
A1
Abstract:
This electrode (14) for limiting current type gas sensors is provided with a dense electrode (5U) which has a metal particle sintered layer (28) and a fine gas introduction path (26) that is formed in the metal particle sintered layer (28). A method for producing this electrode (14) for limiting current type gas sensors comprises: a step for forming a metal particle paste layer (25), which contains carbon nanotubes (22) contained in a binder (24), on a solid electrolyte layer (4); a step for removing the binder (24) by means of sintering at a first temperature in the atmosphere; a step for forming a metal particle sintered layer (28) by means of sintering at a second temperature in an inert gas atmosphere; and a step for forming a fine gas introduction path (26) in the metal particle sintered layer (28) by firing the carbon nanotubes (22) by introducing the atmosphere at a third temperature. The present invention provides: an electrode for limiting current type gas sensors, which enables the achievement of good limiting current characteristics and improved detection sensitivity; a method for producing this electrode for limiting current type gas sensors; and a limiting current type gas sensor which uses this electrode for limiting current type gas sensors.
