Abstract

The objective of this article was to analyze the thermodynamic of a hybrid system, SOFC / ST (SOFC fuel cell and ST steam turbine). The fuel for the analysis was the gas methane (biogas) produced through the anaerobic digestion of the organic residues. The utilized methodology was the energy balance of the system SOFC / ST, considering the internal reforming of methane in the fuel cell, in a way to obtain its electric effectiveness. The result was compared to a conventional combined cycle of gas turbine and steam turbine (GT / ST) for powers between 10 MW and 30 MW. The efficiency of the hybrid system SOFC / ST varied from 61 to 66% in relation to the lower heating value of methane; and the efficiency of the combined cycle GT / ST varied from 41 to 55% within the same power interval. For distributed generation, the SOFC fuel cell is the most efficient technology.
