Abstract

Korea Electric Power Corporation (KEPCO) started a fuel cell project to develop alternative sources of electric power because of the rapid increase in power demand and global environmental problems. For the development of a molten carbonate fuel cell (MCFC), KEPCO started the project in 1993 to develop a 2 kW MCFC system and finished it at the end of 1996. In this project, $ASPEN^+$ was utilized to design the 2 kW MCFC generation system. Based on this simulation, a power generation system was designed and installed for operation and a long term test of internally manifolded 2 kW class MCFC stack. This stack has 20 cells with an effective electrode area of $1000\;cm^2$. It was run at 0.84 V and $150\;mA/cm^2$ and was operated for more than 3,250 hours continuously. This paper describes the system configuration and its control and measurement units. An analysis of the stack performance, the effect of gas utilization ratio, and the stack performance requirements are also discussed.
