Bipolar plates are one of the most important components in fuel cell stacks and have multiple functions. Compared with composite materials, bipolar metallic materials superior electrical thermal conductivity, good mechanical strength, high chemical stability, very wide choice alloys, coating techniques employed to improve their corrosion resistance reduce bottom contact resistance. This paper i...

The proton exchange membrane fuel cell (PEMFC) technology has drawn considerable attention during past two decades and has potential for automotive applications due to high energy density and low impact on environments [1, 2]. Nevertheless, commercialization of fuel cell vehicles still depends on achieving higher volumetric power density and specific power in order to compete with traditionally...

in the polymer electrolyte membrane fuel cells (pemfcs), low corrosion resistance and high interfacial contact resistance (icr) are two controversial issues in usage of aisi 316l stainless steel as a metallic bipolar plate. for solving these problems, investigation and development of different coatings and/or surface treatments are inevitable. corrosion behavior and icr of aisi 316l specimens c...

Abstract The article presents the results of research and an analysis possibility using sinters made graphite powder as a material dedicated to production bipolar plates for low-temperature fuel cell. use metallurgy technology allows materials that meet requirements cell elements construction closing single (bipolar or monopolar plates) interconnectors. morphological chemical powder, microstruc...

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...

Bipolar plates (BPs) are important components of Proton Exchange Membrane Fuel Cells (PEMFC). Graphite-epoxy composites, having a better corrosion resistance than metal-based BPs and mechanical properties graphite BPs, promising alternative. In this study, we tried to develop graphite-epoxy composites meeting the technical US DOE targets for 2020, with proper choice manufacturing conditions tha...
