A titanium-doped Ce0.8Sm0.2O1.9 composite is developed as an anode component of low temperature solid oxide fuel cells running on methane fuel. Crystallographic parameters of (Ce0.8-xTix)Sm0.2O2-delta(0.00 < x < 0.10) are investigated with respect to the amount of titanium. The composites show a single cubic phase with the titanium amount being in the range of 0.00-0.07, while the lattice parameters decrease with increasing titanium content. The (Ce0.8-xTix)Sm0.2O2-delta composites are applied to an anode supported single cell consisting of Ni-(ce(0.8-x)Ti(x))Sm0.2O2-delta anode/Ce0.8Sm0.2O1.9 electrolyte/La0.6Sr0.4-Co0.2Fe0.8O3-delta cathode. Catalytic properties of Ni-(Ce0.8-xTix)Sm0.2O2-delta are inspected with the electrochemical performance and performance stability of the cells in dry methane fuel. The cell with Ni-(Ce0.73Ti0.07)Sm0.2O2-delta (x = 0.07) anode displays a low polarization resistance and an optimum maximum power density (679 mW cm(-2) at 600 degrees C). A performance stability investigation indicates that the cell exhibits a fairly low degradation rate of 3 mV h(-1) during a 31 h operation in dry methane. These findings suggest the application potential of the titanium doped Ce0.8Sm0.2O1.9 for the anode of solid oxide fuel cells. Published by Elsevier B.V.
