NOVELTY - A bipolar plate is made of a composition (C1) comprising: at least an epoxy resin, graphite filler and a metal amine complex as a curing agent for the epoxy resin.    USE - In polymer electrolyte membrane (PEM) fuel cell (claimed) and automobile applications.    ADVANTAGE - The bipolar plate composition is a chemically and physically stable material in polymer electrolyte membrane (PEM) fuel cell environment. The bipolar plates made of the composition can be used at the fuel cell temperatures of -20-160 degrees C i.e. in both low temperature and high temperature fuel cell applications; and are especially suitable for high operating temperatures, such as an operating temperature of 120-160 degrees C as they are also applicable in automobile applications. The bipolar plates have some remarkable advantages compared to the existing bipolar plates, such as machined compressed graphite plates, metal plates or thermoplastic based composite plates; have high electrical and thermal conductive properties; are easy to produce and the costs of the production are low by reason of the inexpensive raw materials (graphite powder and a binder) and a short production time; and have a better dimensional stability. The latent metal amine complex curing agent provides long-standing storage periods without any special storage conditions, and therefore a mixed graphite epoxy composition can be stored under room temperature conditions. The bipolar plates, which are cured by using boron trichloride monoethylamine complex (BCl3-MEA) as a curing agent, have a good resistance to hydrolysis which is an important property in the fuel cell environment. The metal amine complex curing agent allows a rapid temperature rise in the manufacturing process of the plates, and therefore, especially the manufacturing of the large-size kW-class fuel cells is possible in a short production time and fast curing times. The method produces bipolar plates of uniform quality and with high dimension stability. The manufacturing method of the plates is simple, because plates manufactured by this method do not require a long-running cooling stage after the molding. The electrical conductivity of the bipolar plates is around 100 S/cm along the z-axis (through the plate) and usually around 250 S/cm along the x-y-plane (parallel to plate, surface resistance).    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for producing a bipolar plate, involving: preparing the bipolar plate composition (C1); and molding the composition (C1) into the bipolar plate.
