Design and Modeling of 10KW Biofuel Based Solid Oxide Fuel Cell System

With the objective to implement clean, efficient and environmentally friendly technology for electricity generation, the design of a biofuel based SOFC system of 10kW is proposed and modeled theoretically. In particular the focus of this paper is on the modeling of a stack design of biofuel based solid oxide fuel cell system. A lumped parameter modeling approach is implemented in this paper in which all the fundamental equations of fuel cell losses and efficiency are considered for better characterization of the system. On the basis of single cell performance a stack cell system of 10kW along with polygeneration applications is analyzed by different performance curves of stack system including electrical efficiency, heating efficiency, combined heating and power efficiency (CHP), combined cooling and power (CCP) efficiency and combined cooling heating and power (CCHP) efficiency are plotted for different temperature ranges, fuel utilization factor and operating pressure of the system. All the analysis and implementation of system is incorporated in MATLAB software.
