Effect of the Size of Molten Carbonate Fuel Cells on the Temperature Distribution

Abstract:

Molten carbonate fuel cells (MCFCs) are high-temperature fuel cells that use liquid electrolytes composed of molten carbonates such as Li₂CO₃, Na₂CO₃, and K₂CO₃. Electrochemical reactions of MCFCs are exothermic reaction. Consequently, temperature distribution of fuel cells is one of important factors in long-term operation. In this work, the effects of the size of the fuel cell on the temperature distribution were investigated using CFD analysis. It was found that as the length of the gas flow direction and the number of layers of fuel cell increases, the maximum temperature of the cell was increased.
