Replacing the electronically conductive (LaSr)MnO3±δ (LSM) cathode in the LSM/yttrium‐stabilized zirconia (YSZ) system with the mixed ion‐electron conductive (MIEC) (LaSr)(CoFe)O3–δ will promote cathode performance in solid oxide fuel cells (SOFCs) significantly. However, a barrier layer between LSCF and YSZ is necessary for preventing chemical reaction between these two components. In this study,...
Layered perovskite oxide YBaCuCoO5+x (YBCC) was synthesized by an EDTA‐citrate complexation process and was investigated as a novel cathode for proton‐conducting intermediate temperature solid oxide fuel cells (IT‐SOFCs). The thermal expansion coefficient (TEC) of YBCC was 15.3 × 10−6 K−1 and the electrical conductivity presented a semiconductor‐like behavior with the maximum value of 93.03 Scm−1...
In this paper multi‐walled carbon nanotubes (MWCNTs) supported binary AgNi nanoparticles are prepared by chemical reduction of Ag and Ni precursors with NaBH4. Fe/PANI catalyst is obtained by direct pyrolysis of Fe‐doped polyaniline in N2 atmosphere at high temperature. Results show that the Fe/PANI catalyst presents high electroactivity for oxygen reduction reaction (ORR) in alkaline media. The onset...
