Effect of Electrolyte/Cathode Interface Structure on Cathode Performance of Solid Oxide Fuel Cells
Abstract: In this paper, a structured Pt cathode is prepared by flame spraying and slurry coating. The microstructure of the cathode is characterized by SEM. The electrochemical behavior of single cell with the structured cathode is charac- terized by the electrochemical impedance spectroscopy. Effect of electrolyte/cathode interface structure on electro- chemical behavior is discussed. The results show that the electrolyte surface structure has an important influence on cathode polarization. When the temperature is less than 850˚C, the cathode polarization of the cell with a structured electrolyte is approximately 0.3 to 0.75 times of that with a flat electrolyte.
