In this article, a combined heat and power (CHP) system using a solid oxide fuel cell and mini gas turbine is introduced. Since a fuel cell is the main power generating source in hybrid systems, in this investigation, complete electrochemical and thermal calculations in the fuel cell are carried out in order to obtain more accurate results. An examination of the hybrid system performance indicates that increasing of the working pressure and rate of air flow into the system, cause the cell temperature to reduce, the efficiency and the power generated by the system to diminish, and the entropy generation rate and exergy destruction rate to increase. On the other hand, increasing the flow rate of the incoming fuel, the rise in cell temperature causes the efficiency, generated power, and exergy destruction rate of the system to increase.

Hybrid Power

Performance of a solid oxide fuel cell (SOFC) can be enhanced by converting thermal energy of its high temperature exhaust gas to mechanical power using a micro gas turbine (MGT). A MGT plays also an important role to pressurize and warm up inlet gas streams of the SOFC. Performance behavior of the SOFC is sensitively influenced by internal constructions of the SOFC and related to design and operating parameters. In case of the SOFC/MGT hybrid power system, internal constructions of the SOFC influence not only on the performance of the SOFC but also on the whole hybrid system. In this study, influence of performance characteristics of the tubular SOFC and its internal reformer on the hybrid power system is discussed. For this purpose, detailed heat and mass transfer with reforming and electrochemical reactions in the SOFC are mathematically modeled and their results are reflected to the performance analysis. Effects of different internal constructions of the SOFC system and design parameters such as current density, recirculation ratio, fuel utilization factor, and catalyst density in internal reformer on the system performance are investigated and, as a result, some guidelines for the choice of those parameters for optimum operations of the SOFC/MGT hybrid power system are discussed.
