Abstract
A controlled potential electrolysis gas sensor including, as gas electrodesfor 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 potential of the working electrode, the gas electrodesbeing disposed to face an electrolysis solution accommodating portion of an electrolysis tank accommodating electrolytic solution. Each electrodeincludes a noble metal catalyst layer. On the noble metal catalyst layerof at least one of the working electrode and the reference electrode, there is formed a polymer layerhaving ion conductivity and water permeability.
