This paper discusses several systems concepts for molten carbonate fuel cell (MCFC) power plants using natural gas as fuel. In the high-temperature reforming system, natural gas is mixed with a small stream of reformed gas to provide hydrogen for the gas cleanup, and the clean gas is reformed at 800/sup 0/C to 950/sup 0/C and then fed to the anodic side of the fuel cell. In the sensible heat reforming system, a recirculation blower forces a fuel gas mixture through the anode compartment of the fuel cell, where hydrogen is consumed and water vapor is generated. In the internal reforming system, the catalyst for the reform reaction is put into the fuel cell, eliminating the need for gas recirculation as in sensible heat reforming. It is determined that all three system configurations can achieve electrical conversion efficiencies of about 50%.
