Abstract
A process comprising: submerging a fuel cell bipolar plate in a bath comprising nanoparticles and a liquid phase comprising a nanoparticles dispersion agent and wherein the bipolar plate includes an upper surface having a plurality of lands and channels formed therein; removing the fuel cell bipolar plate from the bath so that a coating comprising nanoparticles adheres to the fuel cell bipolar plate; while the coating is wet and before the coating is dried and solidified, removing the coating comprising nanoparticles from the lands of the bipolar plate, leaving coating comprising nanoparticle in the channels; and drying the coating in the channels.
