PREPARATION METHOD OF COPPER-BASED CERMET ANODE FOR SOLID OXIDE FUEL CELL

摘要

A method for preparing a copper-based anode material for a solid oxide fuel cell is provided to make more simply a copper oxide composite sintered body suitable for an anode. A method for preparing a copper-based anode material comprises the steps of dispersing a Y2O3-stabilized ZrO2 or Ce_0.9 Gd_0.1 O_2 powder in a solvent, and adding an acidic copper salt to it; adding a basic copper salt to it; removing the solvent to obtain a dry powder; calcining the obtained powder at a temperature of 300-600 deg.C to obtain a composite powder; and molding the obtained composite powder and heat treating the molded one at a temperature of 1,100-1,250 deg.C.
