摘要: Abstract The allowable tar content in gasification syngas is one of the key questions for exploitation full potential fuel cell concepts with integrated systems. A better understanding interaction between tars and SOFC anodes which leads to carbon formation deposition needed order design systems where extent gas cleaning operations minimized. Model compounds (toluene, benzene, naphthalene) have been used experimental studies represent those arising from biomass/coal gasification. However, use toluene as a model overestimates negative impact real on anode degradation associated formation. In present work, effect its distillation fractions two commercially available anodes, Ni/YSZ (yttria stabilized zirconia) Ni/CGO (gadolinium doped ceria), reported. higher lighter was observed, terms more comparison whole sample. characterization recovered after contact materials revealed shift towards heavier molecular weight distribution, reinforcing view that these reacted anode.
