Abstract Nanostructure cathode material with composition of La0.10Sr0.90Co0.20Zn0.80O5-δ (LSCZO) was synthesized by wet chemical route. The crystallite size was found 47.55 nm and porosity was observed in the structure. The oxygen ion and electron transport phenomena were studied from anode to cathode and vice versa by electrical conductivity and electrochemical performance studies. The conductivity measurements were carried and found 20.29 and 4.87 S/cm2 in air and hydrogen atmosphere, respectively. The area specific resistance (ASR) was observed 0.07 Ω/cm2 at 550 °C. Arrhenius plots were drawn to calculate activation energy and found to be 0.09 eV. Excellent performance of 850 mW/cm2 has been recorded at 550 °C.

基于La0.10Sr0.90​​Co0.20Zn0.80O5-δ阴极的高性能低温固体氧化物燃料电池的制备

摘要 采用湿化学法合成了组成为La0.10Sr0.90​​Co0.20Zn0.80O5-δ的纳米结构正极材料(LSCZO)。发现微晶尺寸为 47.55 nm，并在结构中观察到孔隙率。通过电导率和电化学性能研究，研究了从阳极到阴极的氧离子和电子传输现象，反之亦然。进行了电导率测量，发现在空气和氢气气氛中分别为 20.29 和 4.87 S/cm2。在 550 °C 下观察到的面积比电阻 (ASR) 为 0.07 Ω/cm2。绘制阿伦尼乌斯图来计算活化能，发现为 0.09 eV。在 550 °C 下记录了 850 mW/cm2 的优异性能。
