Abstract

Cermet anode of NiFe(9:1)-La_0.9Sr_0.1Ga _0.8Mg_0.2O₃ (LSGM) (90:10 weight ratio) was studied for direct CH₄ fueled SOFC operating at intermediate temperature. In case of NiFe bimetal anode, power density of the cell decreased drastically after operation under CH₄ feeding condition. On the other hand, mixing Sm doped CeO₂, MgO, or LSGM is effective for improving the long term stability. The cell with NiFe-LSGM anode exhibited much stable power density under CH₄ feeding condition. Deposition of coke was also studied by Raman spectroscopy and no coke deposition was observed after 15 h operation. Since the surface activity of this anode is high, power density was hardly dependent on P_CH4.It was found that NiFe-LSGM10 shows a high tolerance against the coke deposition under CH₄ feeding condition.
