Anode materials with excellent catalytic activity, good stability, and enhanced tolerance to carbon deposition are highly desired for solid oxide fuel cells (SOFCs). Herein, CoFe (CF) nanoalloy catalysts are homogeneously in-situ embedded on Sr₃FeMoO₇ (RP-SFM) efficient electrically conductive perovskite matrix through reduction of Sr₂FeMo_2/3Co_1/3O_6−δ precursor. The particle size of CoFe alloy is in the range of 10–50 nm, and the electrical conductivity enhances from about 8 to 17 S cm⁻¹ to 49-63 S cm⁻¹ after Sr₂FeMo_2/3Co_1/3O_6−δ reduction. The maximum power density of SOFCs with the RP-SFM@CF-SDC(Sm_0.2Ce_0·8O_1.9) composite anode in H₂ fuel reaches to 2.12 W cm⁻² at 850 °C, which is about 1.4 times than that of the SOFCs with traditional Ni-SDC anode. Moreover, the RP-SFM@CF-SDC anodes also demonstrate excellent resistance to carbon deposition and high power density when C₃H₈ hydrocarbon is used as fuel. The improved catalytic activity results from the efficient electronic/ion conductive paths, abundant CoFe active sites, together with the enlarged trip phase boundaries (TPBs).

固体氧化物燃料电池（SOFC）非常需要具有优异催化活性，良好稳定性和增强的碳沉积耐受性的阳极材料。在此，由CoFe（CF）纳米合金催化剂是均匀原位嵌入的Sr ₃ FeMoO ₇（RP-SFM）高效导电的钙钛矿通过矩阵减少Sr中₂钼铁_2/3钴_1/3 ö _6-δ前体。CoFe合金的粒径在10–50 nm范围内，在Sr ₂ FeMo _2/3 Co _1/3 O后，电导率从大约8到17 S cm ^-1增加到49-63 S cm ^-1 _6−δ减少。与RP-SFM @ CF-SDC（钐SOFC中的最大功率密度_0.2的Ce _{0 · 8} ö _1.9）复合H中阳极₂的燃料到达至2.12W¯¯厘米^-2在850℃下，大约是比1.4倍传统的Ni-SDC阳极生产SOFC。此外，当使用C ₃ H ₈烃作为燃料时，RP-SFM @ CF-SDC阳极也表现出出色的抗碳沉积性能和高功率密度。改进的催化活性归因于有效的电子/离子传导路径，丰富的CoFe活性位以及扩大的跳闸相界（TPB）。
