Title:
CONSTANT POTENTIAL ELECTROLYSIS GAS SENSOR AND CONSTANT POTENTIAL ELECTROLYSIS GAS SENSOR MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/286814
Kind Code:
A1
Abstract:
A constant potential electrolysis gas sensor 1 according to the present invention is characterized by comprising: a case provided with a case body 21; an electrode structure 3 including electrodes 31, 32, 33 provided to the case body 21; lead wires 41, 42, 43 connected to surfaces of the electrodes 31, 32, 33; and external electrodes 51, 52, 53 which extend from the outside of the case to the inside of the case, which are provided to the case body 21, and to which the lead wires 41, 42, 43 are connected. The constant potential electrolysis gas sensor is also characterized in that: the external electrodes 51, 52, 53 are disposed such that connection parts CP, of the external electrodes 51, 52, 53 to which the lead wires 41, 42, 43 are connected, are located at a height corresponding to the electrode structure 3; and the case body 21 has holding structures 8 capable of holding a predetermined amount of a protective agent so as to cover the connection parts CP, with respect to the external electrodes 51, 52, 53.
