abstract = {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.},
