Oxy-coal combustion exhibits different characteristics of combustion, flow and heat transfer from those of air-coal combustion, due to the high concentration of CO2 and H2O in the product gases. Using computational modeling, this study investigated t

When synthetic natural gas (SNG) is produced from coal and used as a fuel in the internal reforming molten carbonate fuel cell (ir-MCFC), electric efficiency can be no greater than 31%. This is because there are several exothermic reactions in the pr

The KEPCO Research Institute has developed the Molten Carbonate Fuel Cell (MCFC) since 1993. Recently, a 125-kW MCFC system has been operated at the Boryeong thermal power plant in Korea from December 2009 to March 2010. This system is made up of a 1

To improve the unit cell performance and stability, molten carbonate fuel cell (MCFC) matrices were fabricated using synthetic α-LiAlO 2 powder and they showed mechanical and microstructural stability under thermal cycle tests. The pure α-LiAlO 2 m

The use of a separator to control stack temperature in a molten carbonate fuel cell was studied by numerical simulation using a computational fluid dynamics code. The stack model assumed steady-state and constant-load operation of a co-flow stack wit

Mathematical modeling for the parallel flow Molten Carbonate Fuel Cell (MCFC) 150-cell stack has been made. In the 150-cell stack, all cells are connected in a series. Even though each cell has a different current density distribution, the average cu

LiAlO2 powder is used as a material for molten-carbonate fuel cell (MCFC) matrices. The physical and chemical stabilities of LiAlO2 powder during MCFC operation determine the performance and lifetimes of the cells. Change to the phase and particle si

This work investigated the effect of anode thickness on the anodic overpotential with 100 cm 2 class MCFC single cells. The hydrogen oxidation rate in the molten carbonate is suf- ficiently high, which may lead to weak relation of overpotential with
