摘要： A flow field plate or bipolar plate for a fuel cell, where a surface of the flow field plate is textured or roughened to change the surface morphology of the plate. A conductive coating is deposited on the roughened surface where the roughness of the surface of the plate increases the hydrophilic nature of the coating. Therefore, if the coating is naturally hydrophobic, the surface roughness makes the coating hydrophilic to wick water away. If the coating is a conductive hydrophilic coating, then the surface roughness makes the coating super-hydrophilic, and may counter the effects of surface contamination that would act to make the hydrophilic coating less hydrophilic.

摘要： A bipolar plate for a fuel cell that includes a hydrophilic layer deposited on the bipolar plate to a suitable thickness to satisfy hydrofluoric acid etching for the desired lifetime of the fuel cell. In one embodiment, the hydrophilic layer is a relatively thick silicon dioxide layer that is deposited on the bipolar plate as a colloidal dispersion of silicon dioxide nano-particles in a solvent. The dispersion is dried so that the solvent evaporates to form a film of the silicon dioxide nano-particles on the bipolar plate. A relatively thin layer, generally a metal oxide, is first deposited on the bipolar plate by a CVD or PVD process so that the thin layer has suitable bonding to the bipolar plate. The thicker hydrophilic layer is then deposited on the thin layer, where the bonds between the thick layer and the thin layer are suitable for the fuel cell environment.
