　　A PEMFC (Polymer Electrolyte Membrane Fuel Cell) stack is composed of GDL (Gas Diffusion Layer), MEA (membrane electrode assemblies), and bipolar plates.The electrical resistance of bipolar plates for a PEMFC should be very low to conduct the electricity generated in fuel cells with minimum electrical loss.The resistance of the bipolar plate of a PEMFC consists of bulk material resistance and interfacial contact resistance.The interfacial contact resistance is much larger than the bulk resistance in the case of carbon fiber reinforced epoxy composite bipolar plates due to the resin rich area of composite plates.
