Redox-Stable Anode

摘要

The present invention provides a method of producing a solid oxide fuel cell, comprising the steps of: forming an anode support layer; applying an anode layer on the anode support layer; applying an electrolyte layer on the anode layer; and sintering the obtained structure; wherein the anode support layer and/or the anode layer comprises a composition comprising doped zirconia, doped ceria and/or a metal oxide with an oxygen ion or proton conductivity, NiO and at least one oxide selected from the group consisting of AI₂O₃, TiO₂, Cr₂O₃, Sc₂O₃, VO_x, TaO_x, MnO_x, NbO_x, CaO, Bi₂O₃, LnO_x, MgCr₂O₄, MgTiO₃, CaAI₂O₄, LaAIO₃, YbCrO₃, ErCrO₄, NiTiO₃, NiCr₂O₄, and mixtures thereof. According to the invention, a combination of nickel coarsening prevention due to specific Ni-particle growth inhibitors, and, at the same time, a strengthening of the ceramic structure of the anode support layer and/or the anode layer is achieved.
