AIR ELECTRODE CURRENT COLLECTOR FOR SOLID OXIDE FUEL CELL HAVING EXCELLENT ELECTRICAL CONDUCTIVITY AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: An air electrode current collector is provided to have excellent electric conductivity, to have large contact area of a separator and an air electrode, and to form a current collector with thick thickness by low cost and high efficiency without generating oxidation scale in high temperature. CONSTITUTION: An air electrode current collector(8) comprises an air electrode, and a plurality of sheets formed between the separator and the air electrode. The sheets comprise a flow channel with the shape same with the channel of the separator. A manufacturing method of the air electrode current collector comprises: a step of manufacturing oxide powder slurry; a step of manufacturing sheet by using a tape casting method by the slurry; a step of laminating the plurality of sheets; and a step of heating the sheets, and attaching the sheets by pressurizing the sheets.
