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 کاملEffect of Sealing Gas Washer Design on a PEM Stack Fuel Cell Performance
In this paper we study the performance of a PEM stack fuel cell after 900 hours of operation. We tried to identify any voltage degradation and its causes. Microscopic cracks on some parts of MEA mainly due to uniformity of pressure, stress concentration and elongation of membrane in the edge of GDL has been identified as the most important cause of this gradual degradation. High contact resista...
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 کاملModeling and simulation of a new architecure stack applied on the PEM Fuel Cell
To simulate a new economical architecture for PEM fuel cell and investigate the effectiveness of the introduced structure on the performance, computational fluid dynamics (CFD) code is used to solve the equations for a single domain of the cell namely: the flow field, the mass conservation, the energy conservation, the species transport, and the electric/ionic fields under the assumptions of st...
