    摘要： A flow field plate or bipolar plate for a fuel cell, where a surface of the flow field plate is textured or roughened to change the surface morphology of the plate. A conductive coating is deposited on the roughened surface where the roughness of the surface of the plate increases the hydrophilic nature of the coating. Therefore, if the coating is naturally hydrophobic, the surface roughness makes the coating hydrophilic to wick water away. If the coating is a conductive hydrophilic coating, then the surface roughness makes the coating super-hydrophilic, and may counter the effects of surface contamination that would act to make the hydrophilic coating less hydrophilic.

    摘要： An assembly for a fuel cell including an electrically conductive fluid distribution element including a flow field disposed on a surface of the element, wherein the flow field includes a plurality of channels for carrying the gaseous reactants of the fuel cell. The assembly also includes an electrically conductive member disposed at the surface of the element to serve as a gas diffusion media. The channels of the element include a plurality of sidewalls formed in various orientations, and the orientations of the side-walls form a cross-sectional geometry of the channel such that water collection regions are formed at an interface of the electrically conductive fluid distribution element and the electrically conductive member, and at a bottom portion of the channel.

    摘要： A flow field plate or bipolar plate for a fuel cell that includes a conductive coating having formed nanopores that make the coating hydrophilic. Any suitable process can be used to form the nanopores in the coating. One process includes co-depositing a conductive material and a relatively unstable element on the plate, and then subsequently dissolving the element to remove it from the coating and create the nanopores. Another process includes using low energy ion beams for ion beam lithography to make the nanopores.
