    摘要: An electrically conductive fluid distribution element for use in a fuel cell having a layer of a conductive non-metallic fiberless microporous media. In certain embodiments, an electrically conductive metal is deposited along a surface of the element to form one or more metallized regions. The metallized regions are arranged to contact a membrane electrode assembly (MEA) in a fuel cell assembly, and thus improve electrical conductance at contact regions between the MEA and the layer of media. Methods of making such a fluid distribution element and operating fuel cell assemblies are also provided.

    摘要: A method for depositing a hydrophilic and electrically conductive layer onto a bipolar plate substrate for a fuel cell in a one step process. The method includes mixing a solution of a conductive material, such as gold particles, and a hydrophilic material, such as silicon dioxide particles, in a suitable solvent, such as ethanol. The solution is then deposited on the bipolar plate substrate by any suitable low cost process. Once the solution dries and the ethanol has evaporated, a thin layer of the conductive and hydrophilic particles remains on the substrate. In one embodiment, the conductive particles are significantly larger than the hydrophilic particles to provide both the desirable hydrophilicity and the low contact resistance.
