| Summary: | 碩士 === 國立聯合大學 === 化學工程學系碩士班 === 103 === This study is aimed to evaluate the effects of anode composition and processing conditions on the performance of solid oxide fuel cell. The first part of this study is to prepare anodic catalyst by electroless deposition of nickel on Yttria-Stabilized Zirconia (YSZ) particles. Different processing conditions were tested. Material properties of these catalysts were characterized. The catalyst was used as the anode material of solid oxide fuel cell. The cell performances were analyzed by the linear scanning voltammetry (LSV) and electrochemical impedance spectroscopy (EIS) method. The result found that maximum power density was 7.8 mW/cm2 with low nickel contain in the anode and it reached 22 mW/cm2 with high nickel contain. The study also explored cerium oxide as the additives of anode catalyst. In order to reduce the thickness of the electrolyte layer and to improve cell ion conductivity, anode supported solid oxide fuel cell was also fabricated and tested. During early experiments, we used commercial cathode composite material. Low cell performance was obtained. Therefore, second part of this study was tested the effects of cathode composition on cell performance. The third part studied reforming catalyst for SOFC application. Used electroless plating method to prepare bi-metallic cermet material and copper oxide was added as the third metallic source. The catalyst slurry was coated on the anode surface by tape casting. The cell performance with reforming catalyst was analyzed.
