Resumen:
Bi Ru O and Bi Ru O , have been tested as electrodes on stabilized zirconia at temperatures as low as 500 K. The 2 2 7 3 3 11oxides have been characterized by thermogravimetry under controlled oxygen partial pressure at high temperature and bypotentiometric measurements after controlled cathodic polarization. The oxygen electrode reaction as functions of oxygenpressure and temperature has been studied by impedance spectroscopy. At low temperature, the dependence of thepolarization resistance on the oxygen pressure was analyzed in terms of charge transfer as a rate controlling step.
