Abstract

The development of high-performance anode materials is of great significance for the development of solid oxide fuel cells (SOFCs) fueled by solid carbon. In this paper, the application of PrBaFe₂O_6-δ (PBF)-based layered double perovskite materials in SOFCs with in-situ precipitation of Fe and FeNi alloys was investigated. Ni-doped (PrBa)_0.95Fe_1.7Ti_0.2Ni_0.1O_6-δ (PBFTN) anode material was prepared by sol-gel method. XRD showed that the as-synthesized material exhibited a perovskite structure and remained stable in an anodic reducing atmosphere. XRD, SEM, TEM, and XPS results showed that a large number of uniformly distributed nano-metal particles are precipitated on the surface of the material under reducing atmosphere, which is crucial for improving the output performance of the cell. When pure nano activated carbon was used as fuel, the electrolyte-supported single cell with PBFTN as anode achieved a maximum power density of 698 mW·cm^-2 at 800℃, which is excellent, indicating that it is a potential SOFCs anode material.
