Direct feeding of hydrocarbon fuels to Solid Oxide Fuel Cells (SOFCs) has attracted much attention in recent years. The aim of this paper is to investigate the viability of anode-supported type cells (NiScSZ/ScSZ/LSM-ScSZ) operating with biodiesel fuels (BDFs) derived from Palm, Jatropha and Soybean oils, for realizing carbon-neutral power generation using fuel cells in the temperature range of 700 - 800oC. The results demonstrated that in principle direct internal reforming (DIR) of BDFs in the SOFC anode is viable, but the content of unsaturated components in BDFs should be as lower as possible to suppress performance degradation. Palm-biodiesel, containing highest amount of saturated fatty acid methyl ester (FAME) among tested BDFs, had led to most stable SOFC operation, and the amount of deposited carbon was considerably small compared to the other fuels with higher degree of unsaturation.
