Fe-doped　SrMoO4　(SrMo0.94Fe0.06O4-delta),　synthesized　by　an　EDTA-glycine　complexing　combustion　process,　can　be　easily　reduced　to　SrMo0.94Fe0.06O3-delta　(SMF)　at　850　degrees　C　in　pure　H-2　atmosphere.　The　incorporation　of　Gd0.2Ce0.8O1.9　(GDC)　into　SrMo0.94Fe0.06O3-delta　is　supposed　to　enhance　the　ionic　conductivity　and　catalytic　activity　of　SMF.　Phase　composition　and　chemical　compatibility　of　SMF-GDC　composite　in　both　air　and　H-2　atmosphere　are　confirmed　by　X-ray　diffraction　test.　SMF-GDC　composites　in　different　mass　ratios　are　systematically　investigated　in　terms　of　electrical　conductivity,　electrochemical　performance　and　power　output　with　the　fuel　cells.　With　the　addition　of　GDC,　the　ionic　conductivity　is　able　to　be　improved　and　the　lowest　interfacial　polarization　resistance　is　observed　to　be　0.647　Omega　cm(2)　for　SMF7-GDC3　composite　anode　at　850　degrees　C.　With　SMF7-GDC(3)　as　anode,　the　single　cell　is　able　to　generate　a　maximum　power　density　of　530　mW　cm(-2)　at　850　degrees　C　when　fed　with　pure　H-2　(30　mL　min(-1))　and　demonstrates　a　considerable　stability　with　the　anode　exposed　to　H-2　and　upon　redox　cycling.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
