Abstract:
1. A solid oxide cell obtainable by a process comprising the steps of: depositing a fuel electrode layer on a fuel electrode support layer; depositing an electrolyte layer comprising stabilized zirconia on the fuel electrode layer to provide an assembly of fuel electrode support, fuel electrode and electrolyte; optionally sintering the assembly of fuel electrode support, fuel electrode and electrolyte together to provide a pre-sintered half cell; depositing on the electrolyte layer of the pre-sintered half cell one or more oxygen electrode layers, at least one of the one or more oxygen electrode layers comprising a composite of lanthanum-strontium-manganite and stabilized zirconia to provide a complete solid oxide cell; sintering the one or more oxygen electrode layers together with the pre-sintered half cell to provide a sintered complete solid oxide cell; and impregnating the one or more oxygen electrode layers of the sintered complete solid oxide cell with manganese to obtain a manganese impregnated solid oxide cell, wherein at least one of the one or more oxygen electrode layers comprises a composite of lanthanum-strontium-manganite and stabilized zirconia and the atomic ratio of manganese to lanthanum and strontium in the lanthanum-strontium-manganite is greater than 1.
