| dc.description.abstract | In this paper we present a modified version of the well know model of Bernardi and Verbrugge which was developed to simulate the behavior of Polymer Electrolyte Fuel Cell. The modified version is based on a different treatment of the electrokinetic model equations, the Butler-Volmer equations. Such equations are analytically integrated in the reactive regions of the electrodes, eliminating the main non-linear terms in the full mathematical model. It is shown that the modified Bernardi-Verbrugge is as accurate as the original model, that it allows an extension of the cell current density over which it is possible to find solutions, that the full numerical procedure is very stable, and that the simulations are up to three order of magnitude faster than those performed with the original model. | IT |
