Exergy analysis of advanced heat integration in SOFC power cycles

The presented work investigates the exergy efficiency of different Solid Oxide Fuel Cell (SOFC) system designs. This is done using a thermodynamic SOFC model, as well as other component models built in Aspen Plus. To ensure comparability the influence of different component pathing and reforming options are compared at a fixed stack size. Furthermore the effect of the choice of fuel utilization, oxidant, operating temperature and pressure are studied. During the analysis operating conditions prone to the risk of carbon deposition are excluded. Also the impact on the respective balance of plant is taken into account. Results show, that depending on the system design and parameters the exergy efficiency of the SOFC system can vary between 44.6 and 77.7%.     «
