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 Al 2 O 3 , TiO 2 , Cr 2 O 3 , Sc 2 O 3 , VO x , TaO x , MnO x , NbO x , CaO, Bi 2 O 3 , LnO x , MgCr 2 O 4 , MgTiO 3 , CaAl 2 O 4 , LaAlO 3 , YbCrO 3 , ErCrO 4 , NiTiO 3 , NiCr 2 O 4 , 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. |
