内部改質固体酸化物型燃料電池における燃料極へのメタン拡散と炭素析出

抄録

The distribution of carbon deposition on fuel electrode and degradation of power generation performance in the internal reforming solid oxide fuel cell (SOFC) supplying methane and steam to the fuel electrode were observed. The result show that the degradation in the case of thin fuel electrode is larger than that in thick and the peak of carbon deposition is detected in the range of 10 μm from the fuel electrode surface. In the case of thick fuel electrode, the area where is under about 20 μm from electrolyte can’t observe the obvious carbon deposition.
