Enabling extraordinary oxygen reduction reaction activity of dual alkaline earth-substituted perovskite cathodes for intermediate-temperature solid oxide fuel cells

Ziwei Dong et al.

Summary: Dual alkaline earth-substituted Pr0.94Ba1-2xSrxCaxCo2O5+delta perovskites are investigated as cathodes for intermediate-temperature solid oxide fuel cells. Incorporating Sr2+ and Ca2+ into the lattice leads to a phase transformation from tetragonal to simple cubic perovskite structure. The perovskite catalysts exhibit enhanced electrocatalytic activity due to improved electrical conductivity, oxygen surface exchange, and ionic diffusion rates. The Pr0.94Ba0.6Sr0.2Ca0.2Co2O5+delta cathode shows reduced area-specific resistance and delivers high power density and stability in fuel cell operation.

Effect of nonequivalent substitution of Pr3+/4+ with Ca2+ in PrBaCoFeO5+δ as cathodes for IT-SOFC

Fangjun Jin et al.

Summary: By utilizing a Ca doping strategy, a novel double-perovskite material Pr1-xCaxBaCoFeO5+delta (PCBCF) was successfully prepared, showing promising electrochemical performance for oxygen reduction reactions in intermediate-temperature solid oxide fuel cells. The introduction of Ca2+ effectively reduced thermal expansion coefficient and material costs, while improving oxygen catalytic activity. The optimal composition x = 0.1 demonstrated the best catalytic activity and durability, making it a potential candidate for cathode applications.

Effect of calcium doping on Sm1-xCaxBaCo2O5+δ cathode materials for intermediate-temperature solid oxide fuel cells

Xianglin Liu et al.

Summary: The oxygen-deficient perovskite Sm1-xCaxBaCo2O5+delta was synthesized and studied as cathodes for IT-SOFCs, showing improved conductivity and catalytic activity by partially substituting Ca for Sm. The samples exhibited good chemical compatibility with CeO2-based electrolytes and promising performance in terms of thermal expansion coefficient and area-specific resistance. These double perovskite materials have the potential to be used as cathodes in intermediate-temperature solid oxide fuel cells.
