Abstract
The performance of solid-oxide-fuel-cell anodes based on composites of LSCM and YSZ containing 0.5 wt.% metal catalyst was studied to understand the performance and stability of these anodes. Electrodes containing Pt were found to be stable in CH4 but carbon deposits with granular or filamentous morphologies were found with electrodes containing either 0.5 wt.% Pd or Ni. Carbon deposition with both Pd and Ni was greatly suppressed by the addition of 10 wt.% ceria as a co-catalyst.
