    摘要: A device comprising a membrane electrode assembly, porous diffusion media, and at least one pair of bipolar plate assemblies is provided. The membrane electrode assembly is interposed between a pair of diffusion media substrates, the bipolar plate assembly comprises at least one flow field passage, and the bipolar plate assembly engages the diffusion media substrate. The diffusion media substrate comprises a fibrous matrix defining opposing first and second major faces. The substrate comprises an amount of carbonaceous material sufficient to render the substrate electrically conductive. An anion exchange resin layer engages at least a portion of at least one of the first and second major faces of the diffusion media substrate and/or the flow field passage. The anion exchange resin is configured to eliminate anions through exchange with hydroxyl groups or formation of quaternary ammonium salts.

    摘要: Through holes for flow paths of the fuel cell are formed in a thermoplastic polymer film by a process selected from a group consisting of laser drilling, etching and lithography, an inner side surface of the thermoplastic polymer film is coated with a metal layer, and the through holes are filled with a fuel diffusion material and a catalyst to provide an anode. The procedure is repeated to provide a cathode. Then, the anode and the cathode are placed to oppose each other. A cation conducting polymer membrane is disposed, between the anode and the cathode, and the anode, the cation conducting polymer membrane and the cathode are hot-pressed.

    摘要: The invention relates to a bipolar plate, for fuel cells, characterised in comprising a layer of a hydrophobing material which is soluble in a solvent, on the surfaces thereof. Water forms small droplets on the surfaces of the bipolar plate due to said layer, which are loosely held on the surface of the bipolar plate and which can be reliably removed from the fuel cell even with low flow speeds for the operating gases. The thickness of the layer and thus the hydrophobicity thereof and the electrical contact resistance between the bipolar plate and a contacting electrode may be adjusted in a simple manner, by varying the concentration of the hydrophobing material in the solvent.
