Abstract
Design performances of the fuel cell / gas turbine hybrid power generation systems based on two different fuel cells (PEMFC, SOFC) have been comparatively analyzed. In each system, the fuel cell operates at an elevated pressure corresponding to the compressed air pressure of the gas turbine. Both internally and externally reformed systems were analyzed for the SOFC hybrid system. Component design parameters of 10kW class small systems are assumed. For all hybrid systems, increasing the turbine inlet temperature increases the power portion of the gas turbine. With increasing the turbine inlet temperature, system efficiency decreases in the PEMFC system and the internally reformed SOFC system while that of the externally reformed SOFC system increases slightly. The internally reformed SOFC hybrid system is predicted to exhibit the best system efficiency.
