Abstract
FuelCell Energy, Inc has developed a design for a hybrid powerplant which combines the company’s carbonate Direct Fuel Cell (DFC) with a gas turbine cycle in an ultra high efficiency system. Under a recently completed program supported by the U.S. Department of Energy through the Federal Energy Technology Center (FETC, Morgantown WV), the system design was optimized to eliminate high-temperature developmental components and reduce the overall complexity of the cycle. Modeling studies indicate that the system is capable of operating with fuel-to-electrical LHV efficiencies in the low 70’s with near term fuel cell performance levels. Longer term fuel cell performance gains may provide system efficiencies near 80 percent.
