摘要
The removal characteristics of CO2 in molten carbonate fuel cell (MCFC) were elucidated by the single cell whose electrode area was 81 cm2 and electrolyte was 52Li2CO3/48Na2CO3. The experimental value of the CO2 removal rate from cathode to anode was almost corresponding to the theoretical value. Cell voltage dropped drastically when concentration of CO2 in cathode became 15% or less. This tendency showed strikingly, as concentration of O2 in cathode became lower and lower. The cell performance is influenced with the pO2/pCO2 ratio of the cathode gases, because cell voltage decreases by decreasing the pO2/pCO2 ratio. Therefore, when the pO2/pCO2 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 CO2 in COP3 can be achieved.
