    Abstract: A metallic bipolar plate for use in a fuel cell includes a metallic bipolar plate having one or more channels and a contact surface. The contact surface has a surface roughness defined by a plurality of peaks and valleys wherein at least a portion of the valleys are filled with an electrically conductive material. The contact surface is adapted to contact the anode diffusion layer or the cathode diffusion layer such that the contact resistance occurring at this surface is lower than when the electrically conductive material is not present. A fuel cell incorporating the metallic bipolar plate is also provided.

    Abstract: A method for coating a fuel cell component is provided. The method includes the steps of providing a fuel cell component, and forming a coating on a surface of the fuel cell component with a plasma jet. The step of forming the coating may include applying a coating precursor to a surface of the fuel cell component and then reacting the coating precursor with the plasma jet to form the coating. The step of forming the coating may also include growing the coating on the surface of the fuel cell component by delivering the plasma jet containing the coating precursor.
