Redox-Stable Anode

A solid oxide fuel cell comprising:

• an anode support layer;
• an anode layer;
• an electrolyte layer;
• and
• a cathode layer;
• wherein at least the anode support layer anode layer comprises a composition comprising doped zirconia, doped ceria a metal oxide with an oxygen ion or proton conductivity, NiO and at least one oxide which is selected from the group consisting of Al2O3, TiO2, Cr2O3, Sc2O3, VOx, TaOx, MnOx, NbOx, CaO, Bi2O3, LnOx, MgCr2O4, MgTiO3, CaAl2O4, LaAlO3, YbCrO3, ErCrO4, NiTiO3, NiCr2O4, and mixtures thereof.

A method of producing a solid oxide fuel cell, comprising the steps of:

• forming a structure by a method comprising
• applying an anode layer on an anode support layer;
• applying an electrolyte layer on the anode layer;
• and
• sintering the obtained structure;
• impregnating at least the anode support layer with a composition comprising at least one oxide or precursor thereof which is selected from the group consisting of Al2O3, TiO2, Cr2O3, Sc2O3, VOx, TaOx, MnOx, NbOx, CaO, Bi2O3, LnOx, MgCr2O4, MgTiO3, CaAl2O4, LaAlO3, YbCrO3, ErCrO4, NiTiO3, NiCr2O4, and mixtures thereof;
• 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.
