Abstract: Fuel cells are energy conversion systems, which convert chemical energy of the fuel directly into electrical energy; therefore their conversion efficiencies are not subject to the Carnot limitation. Compared with conventional power generation methods, fuel cells offer some advantages like high-energy conversion efficiency and very low air pollutant emission rate. The solid oxide fuel cell (SOFC) is an all solid state fuel cell operated at approximately 700-1000 C and has been investigated widely, because in addition to the general advantages of fuel cells, the SOFC has several distinct advantages, such as a simple gas supply system without an external reformer, generation of high quality heat, use of a wide variety of fuels and rapid reaction kinetics. In this lecture, after the operation mechanism and structure of SOFC are explained, the evaluation technique of SOFC is illustrated. Finally, the feasibilities of biogas and biodiesel as a fuel for SOFC will be discussed by giving the experimental results of our recent studies.
