Abstract:
1. A fabrication method of a fuel electrode and electrolyte of a solid oxide fuel cell (SOFC) in which a sheet cell including a fuel electrode sheet and an electrolyte sheet is positioned at an upper side of a surface of a fuel electrode pellet, comprising steps of: (a) molding and heat-treating powder, in which a fuel electrode material is mixed with a pore forming agent, so as to prepare a sintered fuel electrode pellet; (b) stacking (i) a fuel electrode sheet fabricated by tape casting using a fuel electrode slurry containing a fuel electrode material and (ii) an electrolyte sheet fabricated by tape casting using an electrolyte slurry containing an electrolyte material, and heat-treating the stacked sheets of the fuel electrode sheet and the electrolyte sheet so as to prepare a sintered sheet cell; and (c) coating an adhesive slurry containing a fuel electrode material on the sintered sheet cell or the sintered pellet and adhering the fuel electrode sheet of the sintered sheet cell and the sintered pellet and then heat-treating it.
