“…Indeed, cobalt‐based cathodes are difficult due to high thermal expansion coefficient, poor stability, and high cost of cobalt element, whereas iron‐based cathodes have lower thermal expansion coefficient, better stability, and lower costs. Thus, in recent years, perovskite oxides based on iron with barium doped in A site such as Ba 0.5 Sr 0.5 Zn 0.2 Fe 0.8 O 3 (BSZF) and Ba 0.5 Sr 0.5 Fe 0.8 Cu 0.2 O 3 (BSFCu) are very considered . BaFeO 3‐δ compound exists in hexagonal, triclinic, rhombohedral, cubic, and tetragonal polymorphic forms where depending on the oxygen content.…”

In this research, new ceramic BaFe 0.8 Ni 0.1 Cu 0.1 O 3-δ powder was synthesized by solid-state reaction method in conventional and microwave furnaces. Then, characterization, structure, and morphology of the resulting powders were studied. For characterization of synthetic powders, X-ray diffraction, powder density gas pycnometer method, particle size analysis, scanning electron microscopy, and energy-dispersive spectroscopy were performed. The results showed that the BaFe 0.8 Ni 0.1 Cu 0.1 O 3-δ powder synthesized in microwave furnace at 1,000°C without soaking time and in conventional furnace at the same temperature with 12-hr soaking time. In addition, the X-ray diffraction results demonstrated that the main peak is shifted to lower angles by substitution iron ions with nickel and copper ions. Furthermore, the crystal structures of powders were hexagonal and tetragonal, and their density were 5.88 and 5.43 g/cm 3 , respectively, in conventional and microwave furnaces. Finally, the morphology and particle size of the synthesized powders were the same in both furnaces.

A series of iron‐based perovskite oxides BaFe1−xCuxO3−δ (x = 0.10, 0.15, 0.20 and 0.25, abbreviated as BFC‐10, BFC‐15, BFC‐20 and BFC‐25, respectively) as cathode materials have been prepared via a combined EDTA‐citrate complexing sol‐gel method. The effects of Cu contents on the crystal structure, chemical stability, electrical conductivity, thermal expansion coefficient (TEC) and electrochemical properties of BFC‐x materials have been studied. All the BFC‐x samples exhibit the cubic phase with a space group Pm3m (221). The electrical conductivity decreases with increasing Cu content. The maximum electrical conductivity is 60.9 ± 0.9 S cm−1 for BFC‐20 at 600 °C. Substitution of Fe by Cu increases the thermal expansion coefficient. The average TEC increases from 20.6 × 10−6 K−1 for BFC‐10 to 23.7 × 10−6 K−1 for BFC‐25 at the temperature range of 30–850 °C. Among the samples, BFC‐20 shows the best electrochemical performance. The area specific resistance (ASR) of BFC‐20 on SDC electrolyte is 0.014 Ω cm2 at 800 °C. The single fuel cell with the configguration of BFC‐20/SDC/NiO‐SDC delivers the highest power density of 0.57 W cm−2 at 800 °C. The favorable electrochemical activities can be attributed to the cubic lattice structure and the high oxygen vacancy concentration caused by Cu doping.
