Abstract
Abstract: The solid oxide fuel cell is considered extremely suitable for electrical power plant application. Both high temperature and intermediate temperature solid oxide full cell performance is investigated using models which are built in Aspen customer model. A new simulation software was used in the present study called Aspen plus V.8.4 software application. The AspenPlusTM is a commercially available process simulator for process analysis. This software offers a convenient and time saving means for chemical process studies, including system modelling, integration and optimization. The performance of high temperature solid oxide fuel cell and intermediate temperature solid oxide fuel cell is evaluated and compared using the same software application. The simulation results showed that, the cell voltage value increases by raising the operating pressure, operating temperature, and hydrogen partial pressure. The electrical power output value from the solid oxide fuel cell is increased simultaneously by increasing the current density. Furthermore; the intermediate temperature solid oxide has a higher cell voltage than the high temperature solid oxide. The simulation results obtained show that the proposed system allows one to reach high efficiencies at rated power levels.
