Abstract
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 AlO, TiO, CrO, ScO, VO, TaO, MnO, NbO, CaO, BiO, LnO, MgCrO, MgTiO, CaAlO, LaAlO, YbCrO, ErCrO, NiTiO, NiCrO, 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.
