Simulation and Parametric Analysis Of a Hybrid SOFC-Gas Turb

Abstract
Combined SOFC-Gas Turbine Power Generation Systems are
aimed to increase the power and efficiency obtained from the technology
of using high temperature fuel cells by integrating them with gas turbines.
Hybrid systems are considered in the last few years as one of the most
promising technologies to obtain electric energy from the natural gas at
very high efficiency with a serious potential for commercial use.
The use of high temperature allows internal reforming for natural gas and
thus disparity of fuel composition is allowed. Also air preheating is
performed thanks to the high operating cell temperature as a task of energy
integration.
In this paper a modeling approach is presented for the fuel cell-gas turbine
hybrid power generation systems, to obtain the sofc output voltage, power,
and the overall hybrid system efficiency.
