TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Fuel Cell Component: The metallic fuel cell component comprises bipolar separator plate (1), i.e. metal foil or stainless steel; flat metallic wires or stainless steel.The metallic fuel cell component also comprises non-conductive polymer.The silane is between the metallic fuel cell component and additional coating.The coating is stable when in contact with or in close proximity to proton exchange membrane and within anode and cathode environment of fuel cell. EXAMPLE - In a vessel, acetic acid solution (5 vol. %) was added to water with stirring. In a second vessel, add the silane to isopropanol with stirring. A solution with isopropanol (10 vol.%) and silane (2 vol.%) to the water/acid solution was added with stirring to form silane coating solution. The cleaned stainless steel plate was submerged to the silane solution, ensuring all air bubbles were gone from the surface to ensure complete coating. Remove the plate and allow it to dry.
