    摘要: A fuel cell electrically conductive element is provided with a polymeric surface comprising a flow field, at least a part of the flow field having a grafted, permanently hydrophilic, polymer coating. The element is made by applying a layer of a monomer mixture of a hydrophilic, ethylenically-unsaturated monomer and a crosslinking monomer to the electrically conductive element surface and polymerizing the applied monomer mixture layer with a plasma whereby the polymerized layer is grafted to the polymeric surface.

    摘要: A fuel cell includes a first electrically conductive plate and a first gas diffusion layer. The first gas diffusion layer is disposed over the first electrically conductive plate. Characteristically, the first gas diffusion layer comprises a first fibrous sheet having fibers coated with an electrically conductive layer. A first catalyst layer is disposed over the first gas diffusion layer and an ion conducting membrane is disposed over the first catalyst layer. The fuel cell also includes a second catalyst layer disposed over the ion conducting membrane with a second gas diffusion layer disposed over the second catalyst layer. A second electrically conductive plate is disposed over the second gas diffusion layer. Methods for forming the gas diffusion layers and the fuel cell are also provided.

    摘要: Fuel cell bipolar plates are made by depositing a pinhole free corrosion resistant and/or a conductive layer on a metal plate using an atomic layer deposition method. In one embodiment, a conductive layer is deposited on an anodized metal plate using atomic layer deposition method. In another embodiment, at least one corrosion resistant metal oxide layer and at least one conductive layer are deposited on a metal plate individually using atomic layer deposition method. In yet another embodiment, a corrosion resistant and conductive metal oxynitride layer is deposited on a metal plate using an atomic layer deposition method.
