520 _ _ |a Anode-supported solid oxide fuel cells (SOFCs) with a state-of-the-art Ni/YSZ anode have been tested insimulated bio-syngas with controlled addition of tars and sulfur as model molecules to study the influenceof impurities on the degradation of SOFCs. The phenol tar causes macro- and micro-scale structuralchanges in the support including erosion, Ni coarsening, and carbon fiber formation. However, the effect of phenol on the cell performance was not pronounced below a content of 8 g/Nm$^{3}$ in the few hundreds of hour test period. On the other hand, the cell responded immediately after 0.5 g/Nm$^{3}$ of naphthalene were added in the fuel. There was no microstructure change and the carbon deposition was found only on thesurface of the support. A stack test with real bio-syngas derived from wood pellets showed more practical problems. The stack showed considerable performance degradation and the test was stopped after 5 hours of operation due to an increase of the pressure drop. There were heavy carbon depositions at the support surface and the Ni mesh current collector. The microstructure change of support was also observed near and under the carbon deposition area, and the Ni metal dusting behavior was observed from the Ni particles in support and Ni mesh current collector. ...
