“…Fig. 1 shows the XRD patterns of the as prepared SFM, SFNM-05, SFNM-10 and SFNM-20 calcined at 1100 °C for 5 h. All the cathode materials show a cubic perovskite structure (JCPDS 70-4093), being consistent with the results reported by other groups [45,46] . The incorporation of Ni does not cause a second phase formation.…”

Cobalt‐free perovskite SrTa _0.1 Mo _0.1 Fe _0.8 O _{3‐

Ta 5+ and Mo 6+ substituted SrFeO 3-δ perovskites were researched as cathodes of intermediate-temperature solid oxide fuel cells (IT-SOFCs). The samples were synthesized with three components, e.g. mono-doped SrTa 0.2 Fe 0.8 O 3-δ , SrMo 0.2 Fe 0.8 O 3-δ and co-doped SrTa 0.1 Mo 0.1 Fe 0.8 O 3-δ . Their phase structure, thermal stability, electrical conductivity and electrochemical catalytic property were researched comparatively. Ta 5+ and Mo 6+ co-doped SrTa 0.1 Mo 0.1 Fe 0.8 O 3-δpossesses better electrochemical catalytic activity than that of the mono-doped SrFeO 3-δ . The performance difference between the mono-doped and co-doped SrFeO 3-δ has a close relation with the different contents of oxygen vacancy in the materials. The synergistic effect derived from Ta 5+ and Mo 6+ co-doping enhances the amount of oxygen vacancies in material, thus resulting in its better electrochemical property. The cells with SrTa 0.1 Mo 0.1 Fe 0.8 O 3-δ as cathode deliver a R p of 0.085 Ω·cm 2 and an output of 931 mW·cm -2 at 800°C.

Polycrystalline Ca0.925Ce0.075Mn0.9Fe0.1O3 were prepared by sol-gel reaction at 1073 K. The compound was analyzed by a powder X-ray diffraction technique and found to be in single phase. The unit-cell parameters and atomic positions were refined using General Structure Analysis to an orthorhombic structure with space group Pnma (#62) a = 5.281 90 (33) Å, b = 7.4968 (45) Å, and c = 5.302 90 (32) Å.
