Nickel-yttria-stabilized zirconia-gadolinia-doped ceria (Ni-YSZGDC) composite anodes were investigated to use butane directly for microtubular solid oxide fuel cells (SOFCs). It was confirmed that mechanical mixing and sintering at 1400 °C for the YSZGDC composites resulted in the formation of a YSZ-GDC solid solution. The n-butane conversion for the cells with Ni-YSZGDC composite anodes was higher than that with Ni-YSZ anode. However, carbon deposition was observed on the Ni-YSZGDC composite anodes after durability test in n-butane. On the other hand, the performance was stable for the cell with the Ni-GDC anode in n-butane due to no carbon deposition. The Ni-GDC anode has a high electrochemical activity of carbon oxidation.
