• The removal characteristics of CO 2 in molten carbonate fuel cell (MCFC) were elucidated by the single cell whose electrode area was 81 cm 2 and electrolyte was 52Li 2CO 3/48Na 2CO 3. The experimental value of the CO 2 removal rate from cathode to anode was almost corresponding to the theoretical value. Cell voltage dropped drastically when concentration of CO 2 in cathode became 15% or less. This tendency showed strikingly, as concentration of O 2 in cathode became lower and lower. The cell performance is influenced with the p O 2 / p CO 2 ratio of the cathode gases, because cell voltage decreases by decreasing the p O 2 / p CO 2 ratio. Therefore, when the p O 2 / p CO 2 ratio is as low as the thermal power plant, it is necessary to add air to cathode for improving the cell performance. Consequently, the reduction target of CO 2 in COP3 can be achieved.
