Microstructures and electrical properties of calcium substituted LaFeO3 as SOFC cathode

The influence of chromium substitution on crystal structure and shift of Néel transition in GdFe1−xCrxO3 mixed oxides

“…It is therefore important to pinpoint that composition range, in which the paramagnetic ordering would be preferential at room temperature. Some attempts of material modification were already made in the case of substitution of rare earth ions [24][25][26] or transition metal cations [27][28][29][30]. As a result the magnetic ordering is destroyed, and when the substituting ion has a different valency the resistivity decreases as well due to the increase in concentration of free charge carriers.…”

Effects of interlayer thickness on the electrochemical and mechanical properties of bi-layer cathodes for solid oxide fuel cells

“…Research has also focused on enhancing the longterm stability of THSOFCs [7e9]. The cathode and cathode/electrolyte interface, where oxygen reduction and transport take place, are believed to play a significant role on the overall SOFC performance and have, therefore, attracted ongoing research efforts [10,11].…”

Synthesis, characterization, and property studies of (La, Ag) FeO3 (0.0≤x≤0.3) perovskites

“…Perovskite-oxides such as LaFeO 3 have found applications in several technologies mainly due to their unique structural features [1][2][3][4][5][6][7]. The properties of such materials are influenced by the type and amount of doping, as well as the synthesis procedure employed to process these materials.…”
