Electrochemical characteristics of the planar electrochemical carbon monoxide sensor with a perfluorosulfonate ionomer film
Abstract Planar electrochemical CO sensors were fabricated and studied. The sensors comprised three electrodes (working, counter and reference) on a substrate and a solution-cast protonated perfluorosulfonate ionomer film, which covered three electrodes and a substrate. The electrochemical characteristics of the present sensors were studied by cyclic voltammetry. It was confirmed that the present sensor worked electrochemically well and detected CO in air by oxidation current.
