Abstract
A method for producing and reactivating a solid oxide cell stack structure by providing a catalyst precursor in at least one of the electrode layers by impregnation and subsequent drying after the stack has been assembled and initiated. The method includes impregnating a catalyst precursor into a cathode of a solid oxide cell stack which already contains an active material (an anode reduction) for example, in the form of Ni/YSZ anodes. Due to a significantly improved performance and an unexpected voltage improvement this solid oxide cell stack structure is particularly suitable for use in solid oxide fuel cell (SOFC) and solid oxide electrolysing cell (SOEC) applications.
