Reviews on Solid Oxide Fuel Cell Technology

Solid Oxide Fuel Cell (SOFC) is one type of high temperature fuel cell that appears to be one of the most promising technology to provide the efficient and clean energy production for wide range of applications (from small units to large scale power plants).This paper reviews the current status and related researches on SOFC technologies.In details, the research trend for the development of SOFC components (i.e.anode, electrolyte, cathode, and interconnect) are presented.Later, the current important designs of SOFC (i.e.Seal-less Tubular Design, Segmented Cell in Series Design, Monolithic Design and Flat Plate Design) are exampled.In addition, the possible operations of SOFC (i.e.external reforming, indirect internal reforming, and direct internal reforming) are discussed.Lastly, the research studies on applications of SOFCs with co-generation (i.e.SOFC with Combined Heat and Power (SOFC-CHP), SOFC with Gas Turbine (SOFC-GT)) and SOFC with chemical production) are given.
