- W2893837072 abstract "The Mo-doped La0.6Sr0.4Fe0.9Ni0.1O3-δ (LSFNM) material is synthesized by a sol-gel method as a SOFC anode. XRD results explain that La0.6Sr0.4Fe0.9Ni0.1O3-δ (LSFN) is decomposed severely above 800 °C in reducing atmosphere, while LSFNM basically maintains the cubic perovskite main phase, and only a small quantity of heterophase appears. Apparently, Mo doping can improve the reduction stability of material. Meanwhile, Mo6+ effectively suppresses the reduction of the Fe4+/Fe3+ electron pair in reducing atmosphere, which enhances the electrical conductivity. In 5% H2-Ar, the conductivity of Mo-doped sample is increased from 0.75 to 2.8 S cm−1 at 800 °C, which is more in line with the requirement of the anode. LSFNM exhibits lower polarization resistance (Rp) than LSFN in wet H2; for example, the Rp values of LSFN and LSFNM at 850 °C are 0.25 and 0.18 Ω cm2. The maximum power density (Pmax) of the LSGM-supported single cell is increased from 740 to 975 mW cm−2 in H2 at 850 °C, and the cell exhibits reasonable stability at 700 °C for 100 h. Thus, it is rational to consider that the LSFNM is a potential material for IT–SOFC anode." @default.
