摘要： A flow field plate for a fuel cell that includes a metal oxide coating that makes the plate hydrophilic. In one embodiment, the metal oxide coating is a thin film to maintain the conductive properties of the flow field plate. The metal oxide can be combined with a conductive oxide. According to another embodiment, the metal oxide coating is deposited as islands on the flow field plate so that the flow field plate is exposed between the islands. According to another embodiment, lands between the flow channels are polished to remove the metal oxide layer and expose the flow field plate. According to another embodiment, the flow field plate is blasted with alumina so that embedded alumina particles and the roughened surface of the plate provide the hydrophilicity.

摘要： A flow field plate for a fuel cell that includes an outer layer of a metal oxide or other material that makes the plate hydrophilic. The particular metal oxide and the thickness of the metal oxide layer are selected so that hydrofluoric acid generated by the fuel cell continuously etches away the layer at a predetermined rate so that a surface of the layer is free of contaminants over the entire life of the fuel cell. If the fuel cell does not employ a perfluorosulfonic acid membrane, then a separate hydrofluoric acid source can be provided that injects a low level solution of hydrofluoric acid into one or both of the reactant gas streams.

摘要： The present invention discloses a method of efficiently manufacturing fuel cells having coated bipolar plates. The present invention contemplates the laser welding together of individual plates already having a coating thereon to form the bipolar plates that are used in a fuel cell. The laser welding of the coated plates together does not result in sensitization of the plates to a magnitude sufficient to cause an undesirable level of corrosion resistance. This result is achieved regardless of the presence of the organic coating in the region of the plates being welded and regardless of the ablating of the organic coating by the laser beam.

摘要： Fuel cells are provided that are at least partially resistant to corrosion, including the use of components that are comprised of materials that are at least partially resistant to corrosion. The fuel cells include subgasket materials and designs, involving geometric arrangements of the subgasket that reduce oxygen permeation from, the cathode to the anode side of the membranes and/or hydrogen permeation from the anode to the cathode side of the membranes. In addition to using protonically non-conductive subgasket materials with lower oxygen and/or hydrogen permeabilities, versus ionomeric subgaskets which are protonically conducting and have high O2 permeation rates, the elimination of the microporous layer (e.g., coated onto the diffusion medium) directly beneath the permeable subgasket materials will also reduce production of corrosive species. The elimination of direct contact between the bipolar plate material surface and PFSA ionomer membrane material also prevents corrosion to the metal bipolar plates.
摘要翻译：提供至少部分抵抗腐蚀的燃料电池，包括使用由至少部分抵抗腐蚀的材料组成的部件。燃料电池包括子衬垫材料和设计，其包括减小从膜的阴极到阳极侧的氧渗透和/或从膜的阳极到阴极侧的氢渗透的子衬垫的几何布置。除了使用具有较低氧和/或氢渗透性的质子非导电子衬垫材料之外，对于质子导电并具有高O 2渗透速率的离聚物亚垫，除了微孔层（例如，直接在可渗透的垫片材料下方涂覆到扩散介质上）也将减少腐蚀物质的产生。消除双极板材料表面和PFSA离聚物膜材料之间的直接接触也可防止对金属双极板的腐蚀。

摘要： A bi-polar plate is provided for a fuel cell stack. The bi-polar plate has improved surface wettability. The bi-polar plate includes a body including at least approximately ninety percent by weight of a metal and defining at least one flow channel. At least about 0.05 percent and up to 100 percent by weight of silicon is disposed on a surface of the at least one flow channel to form a high energy surface to form a high energy surface for the bi-polar plate. This can be achieved by adding from 0.5 to 10 weight % silicon to the steel. The percent of silicon is pre-determined based on a desired wettability of the high energy surface of the at least one flow channel.
