Structural and electrochemical characterisation of Pr0.7Ca0.3Cr1−yMnyO3−δ as symmetrical solid oxide fuel cell electrodes

Evaluation of double perovskite Sr2FeTiO6−δ as potential cathode or anode materials for intermediate-temperature solid oxide fuel cells

“…Fig.12 shows the performance of an SDC electrolyte supported symmetrical fuel cell with the configuration of SFT/SDC/SFT tested under humidified pure H 2 . The maximum power densities are 335 and 221 mW cm À 2 in H 2 at 800 and 750 1C, respectively, which are comparable with that of most of the reported symmetrical electrodes [60,[63][64][65]. The good cell performance in H 2 indicates that SFT should be a promising symmetrical electrode for ITSOFCs.…”

A symmetrical solid oxide fuel cell prepared by dry-pressing and impregnating methods

“…The cell performance is increased by a factor of two after the introduction of Ni. It can be seen that the cell performance in CH 4 is comparable with that in H 2 , but in previous reports the performances of the symmetrical SOFCs in CH 4 were significantly lower than that in H 2 [5][6][7][8][9][10][11]. This may be attributed to the novel structure of the cell and the electrodes.…”

“…Recently a new concept of SOFC using the same material as both anode and cathode has been proposed. This will reduce the number of materials and interfaces, and considerably simplify the structure and fabrication process of the SOFCs [5][6][7][8][9][10][11].…”

Effect of Sm3+ and Sr2+ dopants on the FT-IR, photoluminescence and surface texture of lanthanum chromite nanoparticles

“…Pure LaCrO 3 exhibits orthorhombic symmetry at room temperature and transforms to rhombohedral symmetry at 255 • C [3]. However, the doping of a metal cation in La-and/or Crsites of LaCrO 3 arrests the structures' transformation depending on the conditions of preparation [4][5][6]1,2,[7][8][9][10]. It was reported that undoped LaCrO 3 has a p-type semiconductor nature and their electrical conductivity is essentially due to the 3-d band of the Cr 3+ ions through the formation of cation vacancies [8].…”

“…Substitution at A and B sites or both of LaCrO 3 can result in greatly enhanced electrical properties, such as Ca, Sr and Ni doped LaCrO 3 [8]. Furthermore, several workers [3,4] have reported the infrared spectra of rare earth ortho-chromites, but unfortunately some bands were not assigned.…”
