Efficient methods for the reduction of carbon dioxide emissions into the atmosphere are needed. High efficient power plants with the capability of retaining combustion generated CO2 can offer a valuable contribution to the efficient use of energy and the increase of usage of low-carbon and carbon-free fuels. The Graz cycle, a high efficient closed gas turbine cycle, has been thoroughly studied in terms of thermodynamics and turbo machinery layout. It can be further improved in efficiency by the inclusion of a high temperature fuel cell in the high temperature combustion chamber. This paper investigates possibilities for the integration of a high temperature fuel cell in an improved variant, the S-Graz cycle and discusses major advantages for the operation of the fuel cell in the environment of the Graz cycle.
