The Molten Carbonate Fuel Cell (MCFC) can efficiently generate electric power using a variety of fuels such as natural gas, methanol and the gas produced by coal gasification. In order to reveal the influence of coal gasification gas on the performance of MCFC, we conducted tests using the MCFC generating test facility. A remarkable decrease in cell voltage was observed under high current density. A notable increase in the Nernst Loss is suggested to be a main reason.
