PROCESS FOR PRODUCING ANODE MATERIAL FOR SOLID OXIDE FUEL CELL

摘要

To provide an NiO-GDC composite powder or NiO-SDC composite powder having a uniform composition, which is suitable as an anode material for a solid oxide fuel cell.;A process for producing an anode material for a solid oxide fuel cell, made of a composite powder comprising a composite oxide containing cerium element and gadolinium or samarium element, and oxygen element, and an oxide containing nickel element and oxygen element, which comprises a dissolving step of mixing raw material compounds containing metal elements constituting the above composite powder, at least one organic acid selected from the group consisting of maleic acid, lactic acid and malic acid, and a solvent to obtain a metal elements-containing solution, and a drying/sintering step of drying and sintering the metal elements-containing solution.
