A Study on Performance of Solid Oxide Fuel Cell-Stirling Engine Cycle Combined System- Part I: SOFC Simulation by Programming in Matlab and Modeling in Hysys

In recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. The hybrid system presented in this article produced power with SOFC and Stirling engine. The purpose is to analyze a 50 kW Solid Oxide Fuel Cell that could produce enough thermal energy for a 10 kW Stirling engine working in the hybrid system. The hybrid system analysis is performed by programming in Matlab and modeling in Hysys. Thermodynamics and electrical parameters of the system are calculated in two ways. The results are close to each other and confirmed the validity of calculations.
