Abstract

Carbon is richly reserved in coal, biomasses, and many other nature resources. It is usually used as an energy source through oxygen oxidation reaction. The oxidation is generally realized through combustion which causes serious air pollution. Besides, the conversion efficiency of generating electricity through the combustion process is limited by Carnot efficiency. A direct carbon solid oxide fuel cell (DC-SOFC) is a solid oxide fuel cell (SOFC) directly operated with solid carbon as the fuel. It can convert the chemical energy of carbon into electricity with high efficiency. The concentration of produced CO₂ from a DC-SOFC is so high that enables easy capture and segregation of CO₂. Here we systematically introduce the configuration, reaction process, research and development status, and prospects of DC-SOFC. Especially, we give a comprehensive review concerning research progress in DC-SOFC, including development and fabrication of single cells and stacks, DC-SOFC operating with biomass char and coal as the fuel, and gas-electricity cogeneration using DC-SOFC.
