Research On The Thermodanamics Performance Of Distributed Energy System Based On Fuel Cell And Micro-gasturbine

In this paper, in accordance with the characteristics and assumption of micro-gasturbine with heat recovery system, the thermal performance of MGT at the core for combined cooling heating and power system is analysed in detail based on the first law of thermodynamics by using the Fortran powerful calculation procedures. The tubular SOFC model is established and calculated under the electrochemical reaction and thermal principle of SOFC, the influences on the performance of fuel cells by current density, battery temperature, pressure and other parameters are also analysed. On basis,combining the two systems discussed above into one co-generated system, in which the combustor of MGT is substituted by the SOFC system, the hybrid system is calculated compared with the single micro-gas turbine system. Hoping the results of the paper provide references to the design, integration and optimization of hybrid cycle and distributed energy system.
