Abstract	It is shown that the performances of the oxygen potentiometric sensor can be remarkably improved by electrochemical activation. The electrochemical activation were carried out by firstly employing the oxygen potentiometric sensor as a fuel cell (H2 vs. O2), and then running the fuel cell at a low discharge voltage for some time. This activation effect was valid for sensors domestically prepared under different conditions. On the basis of the literature reports and the experimental observations, the possible reasons for the electrochemical activation have been analyzed. The decrease of the concentration of the oxygen ion (oxide) species at the electrode and the decrease of the electrolyte contribution to the total impedance seemed to be the main reasons that have led to the remarkable improvement of the performances of the oxygen potentiometric sensor after the electrochemical activation.
