陶瓷燃料电池电解质流延膜的烧结工艺及其性能研究

Study of Sintering Technique and Properties of Tape-casting Electrolyte for Ceramic Fuel Cell

本文采用“三明治式多孔夹板”烧结方法制得了均匀致密的、用于燃料电池的固体电解质膜材，用SEM方法观察了膜材的微观形貌，还用复数阻抗频谱仪对烧结膜材的电导性能进行了测定，实验结果表明，所采用的烧结工艺能有效解决单层厚膜烧结中易出现的起翘与开裂问题，所制得的膜材的电性能亦能满足陶瓷燃料电池的要求．

A ' sandwich' sintering method was employed for YSZ electrolyte membranes which were prepared by tape casting.Smooth and dense electrolyte membranes suitable for ceramic fuel cell were obtained. The microstructures and elctricaJ conductivity of sintered tape was determined.The experimental results showed that the sintering technique used is efficient for making electrolytemembrances, and their electronic conductivities were good enough for ceramic fuel cells.
