Electrochemical circuit model of a PEM fuel cell

Abstract

A dynamic circuit model for a fuel cell is presented. The model accounts for flow transients, the reactant partial pressures, as well as loss mechanisms within the fuel cell. For a selected PEM fuel cell design, analyses are performed to examine load transients imposed on the fuel cell. The PSpice programming environment was employed. Such model capability is required to ensure power operation of a fuel cell when controlled by an inverter as would be used in home applications.
