MCFC power plants have been developed in many countries. The efficiencies of MCFC plants are expected to be higher than those of conventional power plants, such as advanced combined cycle power plants. The MCFC stack is the main element and the key technology in MCFC systems is to achieve both high efficiency and long lifetime. Molten carbonate is used as the electrolyte and is known to be a significantly reactive material. The high reactivity of the molten carbonate provides excellent cell reaction rates but accelerates corrosion of cell components. Suitable stack designs and materials to prevent corrosion of cell components are the main focus of the following chapter. Different materials for the anode, cathode, matrix and separator plate are considered. Performance and lifetime data of stack manufacture are given. Internal and external reforming is compared. Different concepts for gas manifolds and gas flow types are discussed. The status of stack technology is given. Furthermore, optimization of operating conditions as another approach to fulfilling the requirements concerning high efficiency over a long time is discussed.
