Metal supported solid oxide fuel cell

Abstract

A reversible solid oxide fuel cell obtainable by a method 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; in any order conducting the steps of: forming a cathode layer by impregnating the cathode precursor layer, and forming an anode layer on the electrolyte layer; characterised in that the method further comprises prior to forming said cathode layer, impregnating a precursor solution or suspension of a barrier material into the metallic support layer and the cathode precursor layer and subsequently conducting a heat treatment.
