The double-perovskite Sr 2 NiMoO 6− δ (SNMO) was investigated as an anode material of a solid oxide fuel cell (SOFC). With a 300μm thick La 0.9 Sr 0.1 Ga 0.8 Mg 0.2 O 3− σ (LSGM) disk as electrolyte and Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3− δ as the cathode, the SNMO anode showed power densities of 819mWcm −2 in hydrogen at 1123K. Moreover, there was no buffer layer between anode and electrolyte, which would reduce design techniques and save design cost. After test no chemical reaction was discovered between anode and electrolyte. The anode exhibited good conductivity and the value was around 60Scm −1 in H 2 . Also it had almost linear thermal expansion from room temperature to 1253K and the average thermal expansion coefficient was about 12.14×10 −6 K −1 , which was quite close to that of La 0.9 Sr 0.l Ga 0.8 Mg 0.2 O 3 (12.17×10 −6 K −1 ) electrolyte.
