AbstractA series of Ca-substituted Sr2Fe1.5Mo0.5O6-delta oxides, Sr2-xCaxFe1.5Mo0.5O6-delta (SCFMO, x=0, 0.2, 0.4 and 0.6), were synthesized and evaluated as potential electrodes for symmetrical solid oxide fuel cells. X-ray diffraction examination showed that all samples maintained cubic perovskite structure in both air and wet hydrogen atmospheres. Temperature programmed reduction measurements indicated that the Ca2+ substitution promoted the catalytic activity of SCFMO toward oxygen evolution reactions. Symmetrical anode fuel cell measurements showed the lowest polarization resistance in humidified hydrogen emerged at x=0.6. Single cells-SC0.6FMO vertical bar La0.9Sr0.1Ga0.8Mg0.2O3(L SGM)vertical bar SC0.6FMO, fabricated via tape-casting and impregnation methods, produced peak power densities of 1.05 W.cm(-2) at 800 V and 0.41 W.cm(-2) at 650 V when operating on hydrogen fuels and air oxidants. These results demonstrate SC0.6FMO is a potential electrode material for symmetrical solid oxide fuel cells.
