Electrochemical performance of Nd1.93Sr0.07CuO4 nanofiber as cathode material for SOFC

Model of infiltrated La1−Sr Co1−Fe O3− cathodes for intermediate temperature solid oxide fuel cells

“…It is reported in the literature that the morphology of the fibers changes dramatically after the heat treatment [71], with the fiber diameter being reduced to 100e300 nm after sintering [37,48]. In accordance with these literature data, in this work we assume a fiber diameter d ¼ 220 nm.…”

Improve electrical conductivity of reduced La2Ni0.9Fe0.1O4+δ as the anode of a solid oxide fuel cell by carbon deposition

“…4 shows the TGA curves of reduced LNF powders treated with methanol, CH 4 and CO, respectively. The slight weight loss between room temperature and about 300 C is most likely due to the loss of the absorbed water [47]. The sharp weight loss at about 300 C corresponds to the oxidation of the deposited carbon [48].…”

Novel cobalt-free cathode material (Nd0.9La0.1)2(Ni0.74Cu0.21Al0.05)O4+δ for intermediate-temperature solid oxide fuel cells

“…This value is also much lower than those of other K 2 NiF 4 -type cathode materials, e.g. Ea¼ 1.31 eV for La 2 Cu 0.8 Co 0.2 O 4 [28] and Ea¼ 1.74 eV for Nd 1.93 Sr 0.07 CuO 4 [29].…”
