Performance analysis of the stack is important to improve performance of molten carbonate fuel cell (MCFC). Many single cells and stacks, which were made with different cell design and the electrolytes such as Li/K carbonate and Li/Na carbonate, were tested to develop performance analysis method of stacks. At first, an equation of the cathode reaction resistance was verified using the single cell test results since cathode reaction resistance is the major factor in MCFC performance. Performance analysis method for single cell was applied to stack. However, parameters of the equation, determined by fitting method were not correct since stack data were scattered, Graphical method for determination of the parameters was developed and was confirmed to determine parameters of stacks with accuracy.
