▎ 摘  要

NOVELTY - The plate has a first layer (12) provided with an electrically conductive hydrophobic layer, where the first layer is anisotropically electrically conductive. A second layer (13) comprises a graphene coating for providing an electrical connection between conductive particles (14) of the first layer. The first layer is arranged to lie in a plane on the fuel cell flow plate and electrically conductive in a direction through the plane and less conductive in a direction in the plane. The first and second layers are applied to a flow plate base (11). USE - Fuel cell flow plate i.e. anode flow plate. Can also be used for cathode flow plate. ADVANTAGE - The graphene coating provides in-plane electrical conductivity and corrosion resistance, and has high wetting transparency to allow hydrophobic property of the first layer to be presented at the surface of the fuel cell flow plate through the graphene coating, so that the fuel cell flow plate is conductive for efficient transfer of power through the fuel cell and hydrophobic to assist in water management. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a fuel cell flow plate. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of a fuel cell flow plate with first and second layers applied to a base.
