Title:
CONTROLLED POTENTIAL ELECTROLYSIS GAS SENSOR
Document Type and Number:
WIPO Patent Application WO/2014/203939
Kind Code:
A1
Abstract:
A controlled potential electrolysis gas sensor provided with, as gas electrodes (10) for detecting gas, a working electrode for electrochemically reacting gas to be detected, a counter electrode with respect to the working electrode, and a reference electrode for controlling the potential of the working electrode, the electrodes facing an electrolytic solution housing part of an electrolytic bath that houses an electrolytic solution (20), wherein each of the electrodes (10) is provided with a noble metal catalyst layer (50), and in the noble metal catalyst layer (50) of the working electrode and/or the reference electrode, a polymer layer (60) having ion conductivity and water permeability is formed.
