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, VOx, TaOx, MnOx, NbOx, CaO, Bi2O3, LnOx, 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.

L'invention concerne une méthode de production d'une pile à combustible à oxyde solide. Cette méthode comprend les étapes consistant à: former une couche de support d'anode; appliquer une couche d'anode sur la couche de support d'anode; appliquer une couche d'électrolyte sur la couche d'anode; et fritter la structure obtenue. Dans l'invention, la couche de support d'anode et/ou la couche d'anode comprend une composition comprenant de la zircone, de l'oxyde de cérium et/ou un oxyde métallique dopé à l'aide d'un ion oxygène ou d'une conductivité protonique, du NiO et au moins un oxyde sélectionné dans le groupe comprenant: AI2O3, TiO2, Cr2O3, Sc2O3, VOx, TaOx, MnOx, NbOx, CaO, Bi2O3, LnOx, MgCr2O4, MgTiO3, CaAI2O4, LaAIO3, YbCrO3, ErCrO4, NiTiO3, NiCr2O4, et des mélanges de ceux-ci. Selon l'invention, on obtient une combinaison de prévention de granocroissance ascendante de nickel, causée par des inhibiteurs de croissance de particules Ni spécifiques, et, simultanément, un renforcement de la structure céramique de la couche de support d'anode et/ou de la couche d'anode.
