The use of lightweight metals for fuel cell bipolar plates is attractive for automotive use. High corrosion resistance and electrical conductivity requirements for fuel cell components, however, preclude most uncoated metals from use. Careful selection of alloy coatings and their constituents can reduce or control the electrochemical corrosion potential and corresponding corrosion rate of the alloy coating. New low-cost alloy coatings are being developed for aluminum that possess the requisite high corrosion resistance and high electrical conductivity. Our current development efforts include novel electrolytic alloys and conductive polymer coatings for aluminum to achieve desired fuel cell component lifetime goals.
