Structural, chemical, and electrochemical properties of co-doped fluorite oxides Ce0.8La0.2−xTlxO2−δ as electrolyte materials for solid oxide fuel cells

Preparation and characterization of La2-xSmxMo1.8Al0.2O8.7 as electrolyte for solid oxide fuel cells

“…This small shift is indicative of the decrease in the lattice parameter(Table 1). The substitution larger size La 3+ (ionic radius 1.03Å) by smaller of Sm 3+ (ionic radius 0.96Å) is caused to decrease the lattice parameter [10,11,12] . To assess the sintering property of LSMAO powders, the sintered density of samples sintered at 950 ℃ for 5 h was measured.…”

“…To assess the sintering property of LSMAO powders, the sintered density of samples sintered at 950 ℃ for 5 h was measured. The relative densities of the sintered LSMAO samples, calculated using equation [10,11,12] :…”

“…where m  is the density measured by Archimedes method and th  is the theoretical density, which is calculated using [10,11,12] :…”

“…The total resistance (Rt) of the sample will be the sum of Rgi and Rgb. The total conductivity (σt) was calculated according to the equation [2,11,12] .…”

Synthesis, structural characterisations, NMR spectroscopy, Hirshfeld surface analysis and electrochemical study of a new organic cyclohexaphosphate, (C 6 H 7 FN) 4 (Li) 2 (P 6 O 18 ) (H 2 O) 6

“…S11, where Rs is the ohmic resistance of the (C6H7FN)4(Li)2(P6O18)(H2O)6 pellet and the connected elements (R// CPE). R is resistance and CPE is a constant phase element representing time-dependent capacitive elements [38].…”
