POTENTIAL STABILIZATION METHOD FOR CONTROLLING CONSTANT POTENTIAL ELECTROLYSIS GAS SENSOR, AND CONTROLLED CONSTANT POTENTIAL ELECTROLYSIS GAS SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a potential stabilization method of a constant potential electrolysis gas sensor, capable of shortening the potential stabilization time, after assembling of the constant potential electrolysis gas sensor, and to provide the constant potential electrolysis gas sensor.;SOLUTION: This potential stabilization method of the constant potential electrolysis gas sensor 100, having a plurality of electrodes 32A, 32B, 32C in an electrolytic solution storage part 3 for storing the electrolytic solution, for detecting the electrolytic current of a test gas flowing between the electrodes connected electrically by the electrolytic solution S; has a constitution, wherein at least one electrode among the plurality of electrodes provided in the controlled potential electrolysis type gas sensor 100 is thin-film electrode formed by sticking an electrode material onto the surface of a polymer film; and at least one thin-film electrode is immersed in pure water and is subjected to heating treatment, before assembling the constant potential electrolysis gas sensor 100.;COPYRIGHT: (C)2008,JPO&INPIT
