碳燃料固体氧化物燃料电池结构研究进展

Direct carbon-fueled solid oxide fuel cells (DC-SOFC) are power generation device that directly converts the chemical energy of carbon fuel into electrical energy through an electrochemical process. It has excellent power generation efficiency, high fuel efficiency and low carbon emissions. However, solid fuels are less mobile than gas and liquid fuels. So, at present, enhancing the solid fuel transfer rate to promote effectively the anode reaction kinetics process, and how to add fuel efficiently and conveniently are the key problems for DC-SOFC. In this paper, the recent progresses of DC-SOFC structure research are reviewed in terms of fuel cell macrostructure and anode micromorphology, and the key problems and development direction of carbon solid oxide fuel cell are also discussed.
