Dynamic Modeling and Simulation of Reformed methanol Fuel Cell System Using Modelica

Abstract

In this paper, a dynamic model of a reformed methanol fuel cell (RMFC) system is developed. The base fuel cell model used in the modeling work was provided by Modelon K.K., using Modelica language. RMFC is a coupled multi-physics system involving fluid mechanics, heat & mass transfer, chemical & electrochemical reaction. Therefore, the dynamic modeling and simulation analysis of RMFC is valuable for optimizing operation parameters, as well as system controller design. The component model of methanol reformer, methanol catalytic burner and high temperature polymer electrolyte fuel cell are developed and integrated into a system model using Dymola®. And the models have been verified by comparison with the experimental data. This model is expected to provide a base for developing the optimal control strategy for the RMFC.
