Direct alcohol-fed solid oxide fuel cells

Abstract Low-temperature solid oxide fuel cells (SOFCs), with an operating temperature of ≤ 600°C, seem to be more advantageous than traditional SOFCs, with an operating temperature of 800–1000°C, due to their durability, affordability, and applicability. It is thought that the potential application areas of direct alcohol-fed SOFCs can be improved further by conducting studies on their fuel accessibility and portability. In this chapter, the results of low-temperature SOFCs for alcohol fuels are compiled. In addition, basic information is given on the working principle behind SOFCs, the cell components, and the electrochemical performance of the system. The studies conducted on alcohol-fed SOFCs and the data obtained were compared with those of hydrogen-fueled SOFCs, and their current situation and the aspects that need to be developed were revealed.
