Numerical studies of the gas channels in the molten carbonate fuel cell |
| 초록 |
The gas channels of the molten carbonate fuel cell (MCFC) have been studied numerically. Distributions of pressure and gas compositions in the anode and the cathode gas channels were observed. The rate constant of the electrochemical reaction was deduced with the value of hydrogen usage. Calculations were made at different values of the reaction rate constant and also at different sizes of gas channels. The commercial fluid dynamics program, Phoenics, was used. In result, when the volumetric velocity is constant and the height of gas channel is changed, the change of the CO2 concentration is bigger than the height of gas channel is thicker. When the volumetric velocity is constant and the rate of generation and consumption is multiplied by 0.5, 1 and 2, the change of the CO2 concentration is bigger than the rate of generation and consumption is bigger. On the other hand, when the linear velocity is constant, the change of the CO2 concentration is bigger than the height of gas channel is thinner. |
