Powders　of　La0.90Sr0.10Al0.97Mg0.03O3-δ　(LSAM)　were　synthesized　by　the　glycine-nitrate　process,　and　then　sintered　at　1500　°C　for　5　h.　Impedance　spectroscopy　at　900　°C　in　air　revealed　that　the　conductivity　of　LSAM　was　1.11×10-2　S·c　m-1.　The　chemical　compatibility　of　LSAM　with　anode　materials　NiO-Ce0.9Gd0.1O1.95　(Ni-GDC),　Sr0.88Y0.08TiO3　(SYT)　and　La0.75Sr0.25Cr0.5Mn0.5O3　(LSCM)　was　characterized　by　X-ray　diffraction,　scanning　electron　microscopy　with　energy-dispersive　X-ray　spectroscopy　and　AC　impedance　spectroscopy.　The　results　indicated　that　SYT　and　LSCM　had　poor　chemical　compatibility　with　LSAM　because　Sr2+,　Ti4+,　Mn3+,　and　Cr3+　diffused　readily　into　the　LSAM　lattice.　The　interdiffusion　of　cations　between　LSAM　and　Ni-　GDC　at　1300　°C　was　limited,　implying　excellent　chemical　compatibility.　The　electrochemical　performance　of　symmetrical　cells　of　the　anode　materials　was　measured　under　hydrogen　atmosphere.　The　area-specific　polarization　resistance　of　Ni-GDC　was　5.12　Ω·cm2　at　800　°C.　An　open-circuit　voltage　of　0.925　V　and　a　power　density　of　19.5　mW·c　m-2　were　obtained　at　800　°C　for　a　550　μm　thick　LSAM　electrolyte-supported　single　cell　(Ni-GDC/GDC/LSAM/GDC/La0.75Sr0.25FeO3).　©　Editorial　office　of　Acta　Physico-Chimica　Sinica.
