Kurzfassung englisch:
tThin films of YSZ, unsupported Ni-Cu 1:1 alloy phases and YSZ-supported Ni-Cu 1:1 alloy solutions havebeen reproducibly prepared by magnetron sputter deposition on Si wafers and NaCl(001) single crystalfacets at two selected substrate temperatures of 298 K and 873 K. Subsequently, the layer properties of theresulting sub- m thick thin films as well as the tendency towards carbon deposition following treatmentin pure methane at 1073 K has been tested comparatively. Well-crystallized structures of cubic YSZ, cubicNiCu and cubic NiCu/YSZ have been obtained following deposition at 873 K on both substrates. Carbonis deposited on all samples following the trend Ni-Cu (1:1) = Ni-Cu (1:1)/YSZ > pure YSZ, indicating thatat least the 1:1 composition of layered Ni-Cu alloy phases is not able to suppress the carbon depositioncompletely, rendering it unfavorable for usage as anode component in sub- m sized fuel cells. It is shownthat surfaces with a high Cu/Ni ratio nevertheless prohibit any carbon deposition.
