The microstructure of the anode in anode-supported solid oxide fuel cells has significant influence on the cell performance. In this work, microtubular Ni-yttria stabilized zircona (Zr_0.8 Y_0.2O₂, YSZ) anode support has been prepared by the phase inversion method. Different compositions of non-solvent have been used for the fabrication of the Ni-YSZ anode support, and the correlation between non-solvent composition and characteristics of the microstructure of the anode support has been investigated. The presence of ethanol or isopropanol in the non-solvent can inhibit the growth of the finger-like pores in the anode support. With the increase of the concentration of ethanol or isopropanol in the non-solvent, a thin dense layer can be observed on the top of the prepared tubular anode support. In addition, the mechanism of pore formation is explained based on the inter-diffusivity between the solvent and the non-solvent. The prepared microtubular solid oxide fuel cells (MT-SOFCs) have been tested, and the influence of the anode microstructure on the cell electrochemical performance is analyzed based on a polarization model.

阳极支撑的固体氧化物燃料电池中阳极的微观结构对电池性能具有重大影响。在这项工作中，微管Ni-氧化钇稳定的氧化锆（Zr _0.8 Y _0.2 O ₂，YSZ）阳极载体已经通过相转化法制备。Ni-YSZ阳极载体的制备已使用了不同的非溶剂组成，并且研究了非溶剂组成与阳极载体的微观结构特征之间的相关性。非溶剂中乙醇或异丙醇的存在可以抑制阳极载体中指状孔的生长。随着非溶剂中乙醇或异丙醇浓度的增加，可以在制得的管状阳极载体的顶部观察到薄而致密的层。另外，基于溶剂和非溶剂之间的相互扩散性来解释孔形成的机理。已测试了制备的微管固体氧化物燃料电池（MT-SOFC），
