Resumo:
The following work presents a study of the simulation of high Fuel Cells temperature,
SOFC, and the operation integrated with gas microturbines into combined cycle. The principal
aim is to reach high fuel utilization efficiencies cycles.
Three mathematical models are developed for the SOFC study and a commercial program
of simulation is used for simulation of the microturbina integrated in to SOFC using and
supplying the exit and entrance data of SOFC, respectively.
It is made an evaluation of the influences of the temperature and pressure in the SOFC
operation, alone and integrated with the micro turbine. Two different configurations are
evaluated: pressurized and atmospheric pressure operating. It is also made an evaluation of these
two systems operating in partial loads.
