Abstract: A method for manufacturing a composite separator plate for a fuel cell stack. The method includes preparing expanded graphite into particles, and dispersing the expanded graphite particles into a polymeric resin. The resin, including the graphite particles, is compression molded to form the separator plate. In one embodiment, the expanded graphite is dispersed into the polymeric resin by mixing it in to the resin. In an alternate embodiment, the expanded graphite is sprinkled into the polymeric resin using an SMC-like process.

Abstract: A flow field plate for a fuel cell that includes a metal oxide coating that makes the plate hydrophilic. In one embodiment, the metal oxide coating is a thin film to maintain the conductive properties of the flow field plate. The metal oxide can be combined with a conductive oxide. According to another embodiment, the metal oxide coating is deposited as islands on the flow field plate so that the flow field plate is exposed between the islands. According to another embodiment, lands between the flow channels are polished to remove the metal oxide layer and expose the flow field plate. According to another embodiment, the flow field plate is blasted with alumina so that embedded alumina particles and the roughened surface of the plate provide the hydrophilicity.
