Claim Text:
1. A method for producing a solid oxide cell stack comprising an internal manifold, an external manifold or a combination of both, the method comprising the steps of: assembling the solid oxide cell stack by arranging a plurality of single solid oxide cells into a stack, each of the plurality of single solid oxide cells containing electrode layers separated by an electrolyte layer; initiating the solid oxide cell stack by undergoing anode reduction; and the method further comprising the steps of: (a) impregnating a catalyst precursor into only a cathode of the solid oxide cell stack by introducing a solution of the catalyst precursor via the internal or external manifold, and (b) subsequently drying the solution of the catalyst precursor, wherein steps (a) and (b) are conducted at least once after the solid oxide cell stack has been assembled and initiated so that the electrode layers become catalytically active.
