Abstract

Sr₂Fe_1.5Mo_0.5O₆ (SFM) is a mixed ionic and electronic conductor which can be used as both anode and cathode materials in intermediate-temperature solid oxide fuel cell. By doping Sm into the Sr-site, the electrical conductivity of SFM is enhanced effectively. The single cell with a configuration of Sr_1.8Sm_0.2Fe_1.5Mo_0.5O₆|La_0.8Sr_0.2Ga_0.83Mg_0.17O_2.815| Ba_0.5Sr_0.5Co_0.8Fe_0.2O₃ obtained maximum power densities of 459, 594, and 742 mW cm^-2 with H₂ as the fuel at 750, 800, and 850 °C, respectively. The results suggest that doping with Sm is a very promising way in enhancing the electrical conductivity of SFM and consequently can greatly improve its anode performance.
