Tolerance Limit of Toluene Content in Wood Gas for Ni/ScSZ Anode SOFC

T. Namioka, T. Naruse, R. Yamane, K. Yoshikawa & K. Waki
The influences of tar concentration in wood gas on anode deterioration were evaluated by single cell test over the first 10 h using toluene as a model tar substance. The electrolyte supported single cells which were composed of Ni/ScSZ cermet anode, ScSZ disk electrolyte and LSM cermet cathode were examined Deterioration behaviors were evaluated by SEM image observation. The operating parameter in this study was the toluene concentration only: the steam to carbon ratio and...
