    摘要: A fuel cell electroconductive element, or bipolar plate, that includes a substrate with a cationic or anionic exchange resin coating deposited thereon, and a method for making the same. The bipolar plate has a fluid flow field formed therein. The ion-exchange polymer is preferably deposited on a region of the surface of the substrate by a process of dip coating or spraying. The resin coating is substantially hydrophobic in nature when dry and substantially hydrophilic when wet.

    摘要: A flow field plate for a fuel cell that includes a metal oxide coating that makes the plate hydrophilic. In one embodiment, the metal oxide coating is a thin film to maintain the conductive properties of the flow field plate. The metal oxide can be combined with a conductive oxide. According to another embodiment, the metal oxide coating is deposited as islands on the flow field plate so that the flow field plate is exposed between the islands. According to another embodiment, lands between the flow channels are polished to remove the metal oxide layer and expose the flow field plate. According to another embodiment, the flow field plate is blasted with alumina so that embedded alumina particles and the roughened surface of the plate provide the hydrophilicity.

    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.
