ELECTROCONDUCTIVE POLYMER COATING ON ELECTROCONDUCTE ELEMENTS IN A FUEL CELL
摘要
A bipolar plate for use in a proton exchange membrane fuel cell having an electrically conductive polymer coated on at least one region of a surface of the plate in contact with a flow field. The coated region is hydrophobic or hydrophilic as compared to an uncoated region of the surface to prevent liquid accumulation. Electroconductive polymer coatings are applied by electrochemical polymerization.
