摘要

本研究采用高温固态反应法合成了 Pr0.5In0.5BaCo3ZnO7+δ (PIBCZ) 作为固体氧化物燃料电池 (SOFC) 的阴极材料。有趣的是，通过一锅法形成了由 Pr0.5-xIn0.5+xBaCo3ZnO7+δ (P0.5-xI0.5+xBCZ)、PrBaCo2O5+δ 和 CoO 三相自组装的复合阴极。PIBCZ 在空气中的平均热膨胀系数（TEC）在 20-900 °C 的温度范围内为 14.0 × 10-6 K-1，其导电率在 800 °C 时达到 20.8 S cm-1。面积比电阻（ASR）和最大功率密度（MPD）在 800 ℃ 时分别达到 0.02 Ω cm2 和 435 mW cm-2。

Self-assembled composite cathode material Pr0.5In0.5BaCo3ZnO7+δ for solid oxide fuel cells

In this study, Pr_0.5In_0.5BaCo₃ZnO_7+δ (PIBCZ) is synthesised by the high-temperature solid state reactions method as a cathode material for solid oxide fuel cells (SOFCs). Interestingly, a self-assembled composite cathode with three phases of Pr_0.5-xIn_0.5+xBaCo₃ZnO_7+δ (P_0.5-xI_0.5+xBCZ), PrBaCo₂O_5+δ and CoO is formed by one pot methode. The average thermal expansion coefficient (TEC) of PIBCZ in air is 14.0 × 10⁻⁶ K⁻¹ in the temperature range of 20–900 °C, and its electrical conductivity reaches 20.8 S cm⁻¹ at 800 °C. The area specific resistance (ASR) and maximum power density (MPD) reach 0.02 Ω cm² and 435 mW cm⁻² at 800 °C, respectively.
