| Résumé | This paper investigated the electrochemical performance of Ni 0.9Mg 0.1O-SDC for hydrogen and methane fueled IT-SOFCs using an electrolyte-supported button cells. The Ni 0.9Mg 0.1O-SDC anode has been chosen based on the premises that the doped-ceria is suitable for intermediate temperatures (550-800°C); that Ni is known as an active metal and good electron conductor; that MgO is a promoter to avoid agglomeration of Ni during reduction and to achieve higher Ni dispersion; and finally, that CeO 2-Sm 2O 3 (SDC) improves oxide ion transport to the cell at this intermediate temperature range. Electrochemical performances under humidified hydrogen and methane were carried out at 650, 700 and 750°C and tested using polarization curve and electrochemical impedance spectra. Adding MgO to NiO-SDC anode improved the maximum power density and lowered the polarization resistance of the cell. ©The Electrochemical Society. |
