摘要： A bi-polar plate is provided for a fuel cell stack. The bi-polar plate has improved surface wettability. The bi-polar plate includes a body including at least approximately ninety percent by weight of a metal and defining at least one flow channel. At least about 0.05 percent and up to 100 percent by weight of silicon is disposed on a surface of the at least one flow channel to form a high energy surface to form a high energy surface for the bi-polar plate. This can be achieved by adding from 0.5 to 10 weight % silicon to the steel. The percent of silicon is pre-determined based on a desired wettability of the high energy surface of the at least one flow channel.

摘要： A flow field plate or bipolar plate for a fuel cell that includes a carbide coating that makes the bipolar plate conductive, hydrophilic and stable in the fuel cell environment. Suitable carbides include, but are not limited to, chromium carbide, titanium carbide, tantalum carbide, niobium carbide and zirconium carbide. The carbide coating is then polished or textured by a suitable process, such as laser or chemical etching, to provide a surface morphology that makes the coating more hydrophilic, and further reduces the contact resistance on its surface.

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.
