Simulation of a tubular solid oxide fuel cell stack using AspenPlusTM unit operation models

摘要: Abstract The design of a fuel cell system involves both optimization the stack and balance plant with respect to efficiency economics. Many commercially available process simulators, such as AspenPlusTM, can facilitate analysis solid oxide (SOFC) system. A SOFC may include pre-processors, heat exchangers, turbines, bottoming cycles, etc., all which be very effectively modelled in simulation software. current challenge is that AspenPlusTM or any other commercial simulators do not have model basic stack. Therefore, enable performing using one these must construct an implemented them. most common approach develop complete programming language, Fortran, Visual Basic C++, first then link it simulator user defined subroutine. This paper introduces different development by utilizing existing functions unit operation modules. developed “AspenPlusTM SOFC” able provide detailed thermodynamic parametric analyses easily extended study entire power consisting without requirement for linking Validation this performed comparison Siemens-Westinghouse 100 kW class tubular Sensitivity major operating parameters, utilization factor (Uf), density (Ic) steam–carbon ratio (S/C), were model, results are discussed paper.
