abstract = {Metal-supported solid oxide fuel cells (SOFCs) are
considered to have a high potential for use in future energy
supply. The introduction of the metallic substrate,
preferentially manufactured by prospective P/M technologies
like tape casting, eases handling and joining. The cell
design features high potential for auxiliary power units
(APU), where the integration of SOFC units into lightweight
stack designs is a challenging task. However, there are
still technical problems to be solved for long-term
operation of metal-supported cells. Especially the
interdiffusion of iron, chromium and nickel at the interface
between ferritic FeCr substrates and nickel-containing anode
materials is known to be a key factor for rapid cell
degradation. In this work, diffusion barrier layers on the
basis of Ce0.8Gd0.2O2 and CeO2 were developed, avoiding
interdiffusion phenomena between the ferritic FeCr substrate
and the Ni/YSZ anode during cell fabrication as well as
during electrochemical operation. After applying these
layers, electrochemical performance could be demonstrated.},
