Abstract

In principle, direct internal reforming of practical biodiesel fuels (BDFs) in a solid oxide fuel cell (SOFC) is viable. However, direct feed of practical BDFs to a SOFC caused severe carbon deposition accompanied by C 2H4 formation, which were more significant for higher degree of unsaturation of BDFs. Performance of SOFC running on BDF can be enhanced by increasing the content of a fatty acid methyl ester (FAME) with lower degree of unsaturation. To suppress formation of carbon and C 2H4, a flexible catalyst composed of inorganic fiber network was applied for the operation of SOFC running on FAMEs. In this study, rather high power density of 0.84 W cm-2 at 0.7 V was achieved in the feed of a mixture of oleic- and palmitic-FAMEs.
