<p>A method for producing a material useful for forming a component for an electrochemical fuel cell is provided. More particularly, the component is formed of a sheet (10) of a compressed mass of expanded graphite particles. The component is treated with a water resistant additive sufficient to provide utility as a component in an electrochemical fuel cell. Preferably, the water resistant additive is a fluoropolymer material. More preferably, the water resistant additive is a polytetrafluoroethylene material. The treatment preferably occurs by coating and/or impregnating the water resistant material in the sheet of graphite particles.</p> |
