Polymer electrolyte membrane fuel cell simulation

Chapter 8 is devoted to the simulation of corrosive dissolution of Pt binary nano-cluster in acid environment, of polymer electrolyte membrane fuel cells. It is well known that under the present catalytic electrode production for low temperature fuel cell, it is necessary to reduce their costs by the proposal of binary platinum nanoclusters PtX (where X are the transition metals Cr, Fe, Co, Ni, Ru), while such nanoparticles may possess high... 

A number of models describing supercapacitor resistor and capacitor behaviors used to mimic their performances in power systems have been reported and include classical equivalent, ladder circuit, and lumped or distributed parameter electrical and Debye polarization cell models [6]. An established design of a dynamic model of the often-used polymer electrolyte membrane fuel cell (PEMFC) is included in MATLAB and Simulink software to simulate performance under varying conditions specific to applications.

Recently, pore network modeling has been applied to simulate the accumulation of liquid water saturation within the porous electrodes of polymer electrolyte membrane fuel cells (PEMFCs). The impetus for this effort is the understanding that liquid water must reside in what would otherwise be reactant diffusion pathways. It therefore becomes important to be able to describe the effect that saturation levels have on reactant diffusion. Equally important is the understanding of how the properties of porous materials affect local saturation levels. This requirement is in contrast to most continuum modeling of the PEMFC, where porous materials are treated with volume-averaged properties. For example, the relationship between bulk liquid saturation and capillary pressures foimd through packed sand and other soil studies are often employed in continuum models. ...

Abstract This chapter describes the use of molecular dynamics (MD) simulations to understand structure and transport processes in polymer electrolytes for energy storage and conversion applications. For batteries, the polymer electrolytes studied with MD techniques have generally been of poly(ethylene oxide) (PEO)-type, while the fuel cell polymer electrolytes have been perfluorosulphonic acid (PFSA) membrane materials. The MD methodology, its benefits and its limitations are explained in the chapter, together with a review of some significant MD studies of polymer electrolytes.
