摘要

在这项研究中，我们成功地展示了一种使用铂-钐掺杂的铈(Pt-SDC)复合阴极的燃料电池制造方法，该方法可以在保持与功能层厚度相同的情况下降低铂含量。采用共溅射法制备了Pt-SDC复合阴极。尽管复合阴极中的铂含量有所下降，但由于Pt-SCD不仅能够在阴极和电解质之间的界面上形成三相边界(TPBs)，而且能够在阴极的整个体积表面形成三相边界，因此我们实现了高性能的燃料电池。该复合阴极表明，Pt-SDC可以通过扩大阴极的TPB位点来提高氧还原反应速率。采用复合阴极制备的燃料电池的性能提高到原始燃料电池峰值功率密度的1.66倍。

Fabrication of Platinum-Samarium Doped Ceria Composite Cathode Using Sputtering Technique

In this study, we successfully demonstrated a fuel cell fabrication method using a platinum-samarium-doped ceria (Pt-SDC) composite cathode, which could reduce the platinum content while maintaining the same thickness as the functional layer. The Pt-SDC composite cathode was deposited by a sputtering process in which two materials were simultaneously deposited by a co-sputtering system. Despite the decreased platinum content in the composite cathode, we achieved high performance of the fuel cell since Pt-SCD was able to form triple-phase boundaries (TPBs) not only at the interface between the cathode and the electrolyte but at the entire volumetric surface of the cathode. This composite cathode revealed that Pt-SDC could enhance the oxygen reduction reaction rate by enlarging the TPB site in the cathode. The fuel cell fabricated in this study with a composite cathode demonstrated improved performance at 1.66 times the peak power density of a pristine fuel cell.
