Abstract
A system-level dynamic model of a p-exchange membrane (PEM) fuel cell, that is capable of characterizing the effects of temp., gas flow, and capacitance, was developed with particular emphasis focused on system transient behavior. The fuel cell system is divided into 3 control vols. and a lumped-parameter model for these sub-systems is established using a combination of intrinsic mechanistic relations and empirical modeling. The dynamic model was simulated with SIMULINK. The anal. illustrated the complicated dynamic interactions between various components and effects within a fuel cell system and it demonstrated the necessity of having sep. control vols. Numerical studies were correlated with a single-cell exptl. study and a protocol for parameter identification was constructed to refine the model. This fuel cell model can predict dynamic behavior and predictions agreed with exptl. results. The model can also be used for the optimization and real-time control of PEM fuel cells installed in practical automotive or stationary applications. [on SciFinder (R)]
