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.

摘要： A method for optimizing a fuel cell diffusion media having a spatially varying mass transport resistance is provided. The method includes at least two passes where a first-pass D/Deff profile for the fuel cell diffusion media is provided and applied to a computational model of the fuel cell having a baseline variable profile. At least one first-pass variable profile resulting from the application of the first-pass D/Deff profile to the computational mode is calculated and compared to a desired variable range. The first-pass D/Deff profile is refined, if necessary, to provide a second-pass D/Deff profile. A relative performance of the fuel cell with a second-pass variable profile resulting from an application of the second-pass D/Deff profile is determined. The second-pass D/Deff profile is refined, if necessary, until the second-pass variable profile has a desirable performance. An effective D/Deff profile is thereby provided.
