The present invention provides a method for producing a reversible solid oxide fuel cell, comprising the steps of: - providing a metallic support layer; - forming a cathode precursor layer on the metallic support layer; - forming an electrolyte layer on the cathode precursor layer; - sintering the obtained multilayer structure; - impregnating the cathode precursor layer so as to form a cathode layer; and - forming an anode layer on top of the electrolyte layer. Furthermore, a reversible SOFC is provided which is obtainable by said method. The method advantageously allows for a greater choice of anode materials, resulting in more freedom in cell design, depending on the desired application.

L'invention concerne un procédé permettant de produire une pile à combustible à oxyde solide (SOFC) réversible, qui consiste: à fournir une couche de support métallique; à former une couche précurseur de cathode sur ladite couche de support métallique; à former une couche d'électrolyte sur ladite couche précurseur de cathode; à fritter la structure multicouche obtenue; à imprégner la couche précurseur de cathode afin de former une couche cathode; et à former une couche anode sur la partie supérieure de la couche d'électrolyte. Au moyen de ce procédé, on obtient une SOFC reversible. Ce procédé permet avantageusement un grand choix de matériaux d'anode, ce qui offre plus de liberté dans la conception de la pile à combustible en fonction de l'application désirée.
