      다국어 초록 (Multilingual Abstract)

      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 the different values of the reaction rate constant and also at different sizes of gas channels. The commercial fluid dynamics program, Phoenics, was used.
      When the volumetric velocity is constant and the height of gas channel is changed, the changes of the CO2 concentration are big when the height of gas channel is thick. When the volumetric velocity is constant and the rates of generation and consumption are multiplied by 0.5, 1 and 2, the changes of the CO2 concentration are big when the rate of generation and consumption is big. On the other hand, when the linear velocity is constant, the changes of the CO2 concentration are big when the height of gas channel is thin.
