“…It has been observed that a marginal shift of (110) peak in the BSMF cathode due to the presence of Mg. When Mg is doped into the cathode, it occupies the B-site of the cathode and leads to lattice parameter (a) enlargement from 3.954 Å to 3.975 Å which led to peak shift similar to that of the earlier reported data [13].…”

The chemical composition of the cathode material influences the performance of the low temperature solid oxide fuel cells (SOFCs). In the present work, two different cathode materials (Ba0.5Sr0.5Co0.2Fe0.8O3 and Ba0.5Sr0.5Mg0.2Fe0.8O3) were prepared to assess the role of Mg in the place of Co on the performance of the SOFC. Symmetric cells were fabricated by using Gadolinium doped Cerium (GDC) electrolyte. From the X-ray diffraction analysis, the lattice parameter was measured as increased from 3.954 Å to 3.975 Å for the cathode with the presence of Mg compared with Co. On the other hand, Mg decreased the electric conductivity (35 ± 1.6 S cm−1) compared with Co doping (56 ± 2.4 S cm−1). Higher porosity (4.8%) was observed in the cathode material with Mg which resulted in more triple phase boundaries and promoted higher gas diffusion. Lower polarization resistance (RP) values (7.95 and 1.07 Ω-cm2) were recorded at 600 °C and 700 °C respectively for the fuel cells fabricated with cathode having Mg compared with Co.

“…According to Yusof and Rahman, BSCF has been reported as a good and effective cathode material due to high conductivity, excellent oxygen transport, catalytic activity, and a potential candidate for a low-temperature solid oxide fuel cell (LT-SOFC) [19]. In their study, the nanocomposite cathode BSCF-samarium-doped ceria (SDC) was developed for LT-SOFC, and the behavior of the nanoceramic powders was examined [19].…”

Ce0.5Sr0.5 (Co0.8Fe0.2)1−x ZrxO3−δ (CSCFZ) powders were synthesized by the sol-gel method and characterized to study structural and electrochemical properties. X-ray diffractometer (XRD) patterns of all samples give nanosized particles of a high-degree crystalline cathode having a cubic-type perovskite structure of space group Pm-3m with the existence of oxygen vacancies in the lattices. The results have the perovskite phase with average crystallite sizes of 26.57 nm, 18.14 nm, 18.13 nm, and 18.12 nm with porosities of 9.93%, 9.87%, 9.50%, and 9.08% for x = 0, 0.1, 0.15, and 0.2, respectively. Scanning electron microscope (SEM) micrographs showed the presence of pores on the microstructure. Average grain sizes of prepared samples found from SEM images were in the range of 105.30–183.02 nm. The partial substitution of zirconium at the B-site shows more stable materials than the host without decreasing the porosity that much. The results of electronic conductivity analyzed by the four-probe dc technique show that the conductivity of synthesized materials increases with the increment of both dopant concentration and temperature by the decrement of area specific resistances. The electrical conductivity of CSCFZ steadily increased with the increment of temperature which reached 42.76 Scm−1 at around 450°C.
