SOFC cell comprising a metallic support 1 ending in a substantially pure electron conducting oxide, an active anode layer 2 consisting of doped ceria, ScYSZ, Ni-Fe alloy, an electrolyte layer 3 consisting of co-doped zirconia based on oxygen ionic conductor, an active cathode layer 5 and a layer of a mixture of LSM and a ferrite as a transition layer 6 to a cathode current collector 7 of single phase LSM. The use of a metallic support instead of a Ni- YSZ anode support increases the mechanical strength of the support and secures redox stability of the support. The porous ferrite stainless steel ends in a pure electron conducting oxide so as to prevent reactivity between the metals in the active anode which tends to dissolve into the ferrite stainless steel causing a detrimental phase shift from ferrite to austenite structure.

L'invention concerne une pile à combustible à oxyde solide comprenant un support métallique (1) se terminant en un oxyde conducteur d'électron sensiblement pur, une couche d'anode active (2) consistant en du cérium dopé, du ScYSZ, de l'alliage de Ni-Fe, une couche d'électrolyte (3) consistant en du zirconium co-dopé basé sur un conducteur ionique d'oxygène, une couche cathodique active (5) et une couche d'un mélange de LSM et une ferrite en tant que couche de transition (6) vers un collecteur de courant cathodique (7) d'un LSM à phase unique. L'utilisation d'un support métallique à la place d'un support anodique Ni-YSZ augmente la force mécanique du support et assure la stabilité d'oxydo-réduction du support. L'acier inoxydable ferritique poreux se termine en un oxyde conducteur d'électron pur afin d'empêcher la réactivité entre les métaux dans l'anode active qui entraîne la dissolution en acier inoxydable ferritique produisant un décalage de phase nuisible entre la structure de ferrite et d'austénite.
