Effect of Terminal Design and Bipolar Plate Material on PEM Fuel Cell Performance
Bipolar plates perform as current conductors between cells, provide conduits for reactant gases, facilitate water and thermal management through the cells, and constitute the backbone of a fuel cell stack. Currently, commercial bipolar plates are made of graphite composite because of its relatively low interfacial contact resistance (ICR) and high corrosion resistance. However, graphite composi...
متن کاملNumerical Modeling of an Innovative Bipolar Plate Design Based on the Leaf Venation Patterns for PEM Fuel Cells
Flow channel design on bipolar plates has a direct effect on Proton Exchange Membrane (PEM) fuel cell performance. It has been found out that the flow field design has a deterministic role on the mass transport and water management, and therefore on the achieved power in PEM Fuel cells. This study concentrates on improvements in the fuel cell performance through optimization of channel dimensio...
متن کاملNeural Network Based Model for a PEM Fuel Cell System
Usually, modelling of fuel cell systems uses complex expressions, based on the knowledge of physicalchemical phenomena. These models require a good knowledge of the parameters involved in the processes that, in many cases, are difficult to determine. A solution to avoid this difficulty consists in using black-box models, such as those based on artificial neural networks (ANN). This paper presen...
متن کاملPEM fuel cell electrodes
The design of electrodes for polymer electrolyte membrane fuel cells (PEMFC) is a delicate balancing of transport media. Conductance of gas, electrons, and protons must be optimized to provide efficient transport to and from the electrochemical reactions. This is accomplished through careful consideration of the volume of conducting media required by each phase and the distribution of the respe...
متن کاملDesign and Investigation of Honeycomb End Plates for PEM Fuel Cells
In this article a new structure of PEM fuel cell end plate is presented. The new structure is known as a honeycomb sandwich panel. Several properties of the presented structure, such as mechanical and thermal behavior, as well as its advantages and disadvantages are introduced. The aim of this paper is to reduce the weight of the while maintaining a better compression force on the PEM fuel cell...
