The crystal defects structure, thermal expansion coefficients, electrical transport property, redox cycling stability, and electrochemical performance of Sr2FeMo0.6Mg0.25Al0.15O6(SFMMA) double perovskite material as a high-performance anode for solid oxide fuel cells (SOFCs) were investigated. The SFMMA has a tetragonal structure of I 4/m at room temperature, but transforms into a cubic structure of at 400℃. The real structure of SFMMA should be in the form of Sr2(Fe0.75Mg0.25)(Mo0.6Fe0.25Al0.15)·O6-δ, generating a plenty amount of anti-site defects FeB' and -FeB-O-FeB'-bonds formed in the crystal lattice, which are beneficial to the formation of oxygen vacancies and migration of oxygen ions. The thermal expansion coefficients of SFMMA anode are 13.0×10-6 K-1 and 17.6×10-6 K-1 at 25-400℃ and 400-900℃, respectively. The electrical conductivity of SFMMA is greater than 35 S/cm in the operating temperature range of 600-900℃. The SFMMA anode shows a fast oxygen surface exchange kinetic and an excellent redox cycling stability. The area specific resistances of SFMMA/La0.4Ce0.6O2(LDC)/La0.8Sr0.2Ga0.8Mg0.2O3(LSGM)/LDC/SFMMA symmetrical half-cell are 0.096, 0.142, 0.239 Ω·cm2 and 0.447 Ω·cm2 at 900, 850, 800℃ and 750℃ in wet H2(3% H2O, 50 mL/min), respectively. The electrolyte supported single cell with the configuration of SFMMA/LDC/LSGM (300 μm)/PrBa0.5Sr0.5Co1.5Fe0.5O5+δ can deliver a maximum power density of 886 mW·cm-2 at 850℃.

研究了固体氧化物燃料电池Sr2FeMo0.6Mg0.25Al0.15O6(SFMMA)双钙钛矿阳极的晶体缺陷结构、热膨胀性能、电荷传输特性、氧化还原稳定性以及电化学性能。结果表明:SFMMA室温下为I4/m四方结构,400℃时材料转变为立方结构。SFMMA材料的实际晶体结构式为Sr2(Fe0.75Mg0.25)(Mo0.6Fe0.25Al0.15)O6-δ,材料晶格中含有大量反位缺陷FeB'以及—FeB—O—FeB'—键,有利于氧空位的形成及氧离子的迁移扩散。SFMMA的热膨胀系数在25~400℃和400~900℃范围内分别为13.0×10-6 K-1和17.6×10-6K-1,在氢气气氛下600~900℃温度范围内电导率超过35 S·cm-1,并且具有较快的氧表面交换特性以及非常优异的氧化还原循环结构稳定性。在900,850,800℃和750℃时,湿润H2(3%H2O,50 mL/min)气氛中,SFMMA/La0.4Ce0.6O2(LDC)/La0.8Sr0.2Ga0.8Mg0.2O3(LSGM)/LDC/SFMMA对称半电池面比电阻分别为0.096,0.142,0.239 Ω·cm2和0.447 Ω·cm2。以SFMMA为阳极组装电解质支撑型单电池SFMMA/LDC/LSGM(300 μm)/PrBa0.5Sr0.5Co1.5Fe0.5O5+δ,850℃时电池最大功率密度可达886 mW·cm-2。

The crystal defects structure, thermal expansion coefficients, electrical transport property, redox cycling stability, and electrochemical performance of Sr2FeMo0.6Mg0.25Al0.15O6(SFMMA) double perovskite material as a high-performance anode for solid oxide fuel cells (SOFCs) were investigated. The SFMMA has a tetragonal structure of I 4/m at room temperature, but transforms into a cubic structure of at 400℃. The real structure of SFMMA should be in the form of Sr2(Fe0.75Mg0.25)(Mo0.6Fe0.25Al0.15)·O6-δ, generating a plenty amount of anti-site defects FeB' and -FeB-O-FeB'-bonds formed in the crystal lattice, which are beneficial to the formation of oxygen vacancies and migration of oxygen ions. The thermal expansion coefficients of SFMMA anode are 13.0×10-6 K-1 and 17.6×10-6 K-1 at 25-400℃ and 400-900℃, respectively. The electrical conductivity of SFMMA is greater than 35 S/cm in the operating temperature range of 600-900℃. The SFMMA anode shows a fast oxygen surface exchange kinetic and an excellent redox cycling stability. The area specific resistances of SFMMA/La0.4Ce0.6O2(LDC)/La0.8Sr0.2Ga0.8Mg0.2O3(LSGM)/LDC/SFMMA symmetrical half-cell are 0.096, 0.142, 0.239 Ω·cm2 and 0.447 Ω·cm2 at 900, 850, 800℃ and 750℃ in wet H2(3% H2O, 50 mL/min), respectively. The electrolyte supported single cell with the configuration of SFMMA/LDC/LSGM (300 μm)/PrBa0.5Sr0.5Co1.5Fe0.5O5+δ can deliver a maximum power density of 886 mW·cm-2 at 850℃.
