Abstract
A method of manufacturing a fuel cell bipolar plate comprising first and second thermoformed plates. The thermoformed plates comprise at least one thermoplastic polymer. The method includes providing film cast resin mixture and forming it into a substantially flat sheet having first and second opposing major surfaces. The sheet may be preheated to a predetermined temperature and thermoformed thereby creating separator plates of a desired size and shape. First and second plates are joined to form an integral bipolar plate.
