Abstract
Provides results of a study of the performance of the hybrid systems based on the fuel cell stack developed by Siemens-Westinghouse coupled with four different commercially available recuperated micro-turbines.
Researchers studied the by developing appropriate simulation models validated with available data. Full and part load performance of those systems are presented and discussed. Study results revealed that the smaller the micro-turbine coupled with the Siemens-Westinghouse SOFC generator, the more efficient the corresponding hybrid system. Researchers also observed that when the power requirements are low, the designer may choose a larger micro-turbine than the required, as the system operates efficiently also at higher loads than the base and could satisfy peak energy demands.
