Anode deterioration behavior by tar in wood gas in a SOFC was observed with a SEM and a SEM-EDS. It was found that Ni particles disappearance took place at lower tar concentration than carbon deposition took place. Therefore, we suggested that disappearance of Ni be the criterion for judgment of anode deterioration. Based on the definition of anode deterioration, tolerance limit of tar concentration in wood gas was determined as follows; <1 g/Nm3 at 1073 K, and 3 g/Nm3 at 1173 K. The tolerance limit at 1173 K for the fuel cell is one to two orders of magnitude higher than the tolerance limit for ICEs. This mitigation would be one of the advantages of installing SOFCs instead of ICEs for power plants fueled by wood gas.

用扫描电子显微镜和扫描电子能谱仪观察了焦油在SOFC木材气中的阳极劣化行为。结果表明，较低焦油浓度下镍颗粒的消失比碳的沉积更明显。因此，我们建议将Ni的消失作为判断阳极劣化的标准。根据阳极劣化的定义，确定木材气中焦油浓度的容忍极限为：在1073 K <1 g/Nm3，在1173 K < 3 g/Nm3。燃料电池在1173 K时的公差极限比内燃机的公差极限高一到两个数量级。这种缓解将是安装sofc而不是以木气为燃料的发电厂安装ice的优势之一。
