“…As shown in Figure 10(B), the open‐circuit voltage of the single cell at 600, 650, and 700°C are 1.045, 1.028, and 1.020 V, respectively. And, at 700°C, the peak power density of the single cell is about 0.75 W cm −2 , higher than other reports (0.47 W cm −2 @700°C, BZCY synthesized by Pechini method, 57 besides the cathode paste is prepared using La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3 and BaZr 0.1 Ce 0.7 Y 0.2 O 3‐δ ; 0.27 W cm −2 @700°C, BZCY synthesized by SSR, 13 and BaCe 0.4 Pr 0.4 Y 0.2 O 3 is used as the positive electrode material).

For the sake of enhance the sinter ability and electrical conductivity of BaZr0.1Ce0.7Y0.2O3‐δ (BZCY) electrolytes, a modified aqueous gel‐casting method was applied to synthesize high sintering active and high conductive BZCY nano‐powders. The new approach makes it easy to obtain pure perovskite. The highly sintering active purity‐phase of BZCY nano‐powder (particle size of 50∼100 nm) was obtained by calcining at 1100°C for 2 h. Nano‐powders effectively reduce the sintering densification temperature and successfully prepare BZCY electrolyte with relative density > 96 % at 1450°C, and promote grain growth with an average grain size of 2.36 μm. Benefiting from this, improved electrical conductivities (e.g., 12.4×10−3 S cm−1 at 700°C, in wet air) are obtained. The NiO‐BZCY/BZCY/LSCF‐BZCY anode‐supporting single cell shows a peak power density of 0.75 W cm−2 at 700°C while taking ambient air as oxidants and wet H2 (∼3 vol.% H2O) as fuels.

Herein, the phases, defect formation energies, and electrical properties of nominal Sn‐doped LaNb1–xSnxO4–0.5x and A‐site deficient La1–xNbO4–1.5x materials are reported. LaNb1–xSnxO4–0.5x shows a solid‐solution limit close to x = 0.03 with the defect formation energy of ≈4.13 eV. Higher conductivities are observed under wet than dry conditions, suggesting a considerable protonic contribution in the Sn‐doped materials. The calculated defect formation energy of ≈9.18 eV for creating La vacancies in La sublattice in LaNbO4 agrees well with the fact that there are mixed dominating parent LaNbO4 and minor orthorhombic La0.33NbO3 phases in nominal La1–xNbO4–1.5x samples. The electrical property studies reveal no proton conduction but strong n‐type electronic conduction in La1–xNbO4–1.5x from the minor La0.33NbO3 phase.
