Abstract: The tendency of using fuel cell seems to be much accepted for the energy sources in the nearly future, therefore, the primary study for the molten carbonate fuel cell or MCFC in Thailand is necessary for fuel cell development. This special research project is the study of the performance and characteristic of molten carbonate fuel cell which aims to investigate the effect of anode and cathode gases. Firstly, the ASPEN PLUS 10.2 was used to determine the amount of moisture which flow with the anode gas before feeding to the fuel cell in order to prevent the carbon formation. Secondly, the 10 ?10 cm cell was operated at 650 ?C and 1 atm. At anode, flowrate of H2 was varied and it was found that the cell voltage and power density are increased when raising the H2 flowrate whereas the cell polarization decreased. In addition, the H2:CO2 ratio was varied between 30:70 and 90:10 at constant total flowrate. It was found that the high H2:CO2 results in higher cell voltage and power density than that of low H2:CO2 at the same current density. Furthermore, at constant ratio of H2:CO2 the high total flow produces higher current density than thatof low total flow. At the condition of low utilization or excess H2, the power density does not increase with the H2:CO2 ratio because of the limitation of fuel cell active area. At cathode, the flowrate of CO2 was adjusted at constant O2 flowrate. It was found that the high CO2 flowrate results in higher power density than that of low CO2 flowrate at the same current density. In addition, the power density is also increased with the increasing the flowrate of O2 at constant CO2 flowrate. Nevertheless, the power density is affected by N2 at low utilization. In other word, the power density decreased when the N2 increased because N2 occupied the active area and the reaction of O2 and CO2 is blocked. As a result, the ohmic loss is the main factor that reduces the cell voltage and power density. Moreover, steam reforming process in the CH4 biogas plant which produces high ratio of H2:CO2 may be the most suitable process when compare to the autothermal and partial oxidation processes which produces the lower H2:CO2 as a feed in molten carbonate fuel cell.
