    摘要： The present invention provides an electrically conductive element for a proton exchange membrane fuel cell having low electrical contact resistance and high corrosion resistance. The conductive element comprises a corrosion susceptible metal substrate with a surface, which is preferably treated to activate the surface (i.e. to remove a passivation layer of oxides from the surface) with an acidic treatment solution. The treated surface is then overlaid with an electrically conductive, corrosion-resistant, protective coating to protect the substrate re-forming a passivation layer while exposed to the corrosive environment of the fuel cell. The present invention also provides methods of preparing an electrically conductive element to have low electrical contact resistance and high corrosion resistance.

    摘要： One variation may include a method which may include depositing a hydrophilic coating over at least a portion of a fuel cell bipolar plate. The bipolar plate may include a reactant gas header opening communication with the plurality of tunnels. Moreover, the tunnels may be communicating with a plurality of channels which may be defined by reactant gas flow field which may include a plurality of lands. At least a portion of the hydrophilic coating may be reacted with the material including a hydrophobic group which may provide a hydrophobic portion. Thereafter, at least a portion of the hydrophobic portion comprising oxidizing the hydrophobic group may be removed in order to regenerate the hydrophilic coating.
