Development of bipolar plates for fuel cells from graphite filled wet-lay material and a thermoplastic laminate skin layer
In this paper, a method with the potential to rapidly produce thermoplastic polymer composite bipolar plates with improved formability and hrough-plane conductivity is described. In our earlier work, it was reported that composite bipolar plates made with graphite filled wet-lay materials xhibited excellent mechanical properties and in-plane electrical conductivity. However, the through-plane c...
متن کاملThe development of economical bipolar plates for fuel cells
One of the major challenges in the production of economical polymer electrolyte membrane (PEM) fuel cells for automotive applications is the development of materials for the generation of bipolar plates which meet all the property requirements and can be readily manufactured to impart fine channels for transporting hydrogen and oxygen. Bipolar plates can be made from various materials with the ...
متن کاملEffect 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 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...
متن کاملPreparation and Properties of Various Molecular Weights Poly(oxyalkylene)-amine bearing DGEBA Epoxy Functionalizing Multiwalled Carbon Nanotube /Polypropylene Composite Bipolar Plates for Polymer Electrolyte Fuel Cells (PEMFCs)
Multiwalled carbon nanotubes (MWCNTs) were covalently modified with different molecular weights 400 and 2000 poly(oxyalkylene)-amine bearing DGEBA epoxy (POA400-DGEBA and POA2000-DGEBA) oligomers via a grafting method. The weight-average molecular weights of POA400-DGEBA and POA2000-DGEBA were measured as 1623 and 9231 with polydispersity indices (PDIs) of 2.3 and 1.6, respectively. The oxidize...
