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.
