%X In fuel electrodes for solid oxide electrolysis cells (SOECs) several degradation phenomena can be found after operation for prolonged duration. The agglomeration, especially the depletion of nickel in the active electrode, is the most pronounced degradation within steam electrolysis. Operating SOECs in co-electrolysis mode, coke formation in the fuel gas electrode can lead to further degradation. For nickel catalysts in methanol synthesis copper nickel alloys are known to inhibit coke formation. Therefore copper nickel alloys are interesting candidates for catalysts in SOEC fuel electrode functional layer as they might be beneficial for the suppression of nickel depletion as well.There are many possible manufacturing routes for copper nickel alloy catalysts in solid oxide fuel or electrolysis cells. Most frequently used is the impregnation route. Disadvantages of this approach are time expanse and multiple infiltration and heating steps. In this talk alternative manufacturing routes will be pointed out. Analytical characterization will be shown.
