We present a model of the cathodic region in a Proton Exchange Membrane (PEM) fuel cell, where a segmented electrode is considered. The model, based on the discrete geometric approach, couples a discrete formulated steady state current conduction problem in a non isotropic medium with electrochemical reaction at the catalyst layer described by means of the Boutler-Volmer equation. The model allows to analyze either the constant voltage operation or the constant current operation of the fuel cell.

Abstract
We present a model of the cathodic region in a Proton Exchange Membrane (PEM) fuel cell, where a segmented electrode is considered. The model, based on the discrete geometric approach, couples a discrete formulated steady state current conduction problem in a non isotropic medium with electrochemical reaction at the catalyst layer described by means of the Boutler-Volmer equation. The model allows to analyze either the constant voltage operation or the constant current operation of the fuel cell.File in questo prodotto:
