摘要： A separator assembly for use in a stack of electrochemical cells is provided, having a first conductive metallic substrate with a first surface and a second conductive metallic substrate with a second surface, wherein each of the first and second surfaces are overlaid with an ultra-thin electrically conductive metal coating. The first and second surfaces form electrically conductive paths at regions where the metal coating of the first and second layer contact one another. The contact of the surfaces overlaid with metal coating is sufficient to join the first and second substrates to one another. Preferred metal coatings comprise gold (Au). Methods of making such separator 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.
