| Research Abstract |
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.
