Abstract: A flow field plate for a fuel cell that has one or more outer layers that makes the plate more conductive and hydrophilic. In one embodiment, the coating is co-deposited as combination of a conductive material and a metal oxide coating. A suitable conductive material is gold and suitable metal oxides include SiO 2 , HfO 2 , ZrO 2 , AI2O 3 , SnO 2 , Ta2O 5 , Nb2O 5 , MoO 2 , IrO 2 , RuO 2 and mixtures thereof. The conductive material and metal oxide can also be deposited as two separate layers, where the metal oxide is the outer layer. According to another embodiment, a metal layer is deposited on the plate with nanopores that provide the hydrophilicity. Also, doping ions can be added to the metal oxide to provide low fluoride solubility of the coating to control the rate that hydrofluoric acid etches away the oxide layer.

Abstract: 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.

Abstract: 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.
