摘要： The present invention relates to an electrically conductive element (e.g. bipolar plate) for a fuel cell which has an improved adhesive bond. The conductive element generally comprises a first and a second conductive sheet, each having a surface that confront one another. The surfaces that confront one another are overlaid with an electrically conductive primer coating providing corrosion protection and low contact resistance to said first and said second sheets respectively in regions where the first and second sheets contact one another. The first and said second coated surfaces are joined to one another by an electrically conductive adhesive which provides adhesion of said first and said second coated surfaces of said sheets at the contact region. Further, the present invention contemplates methods to form such an improved bond in an electrically conductive element.

摘要： Corrosion resistant, manganese-stabilized austenitic stainless steels with a low nickel content are used in bipolar plates, methods for fabricating the bipolar plates, and polymer electrolyte membrane (PEM) fuel cells comprising the bipolar plates. The bipolar plates are formed from high-manganese austenitic stainless steels comprising, in weight percents, 4.0 to 35 manganese, 0.5 to 1.5 nickel, 17 to 20 chromium, 0.2 to 0.5 nitrogen, up to 0.075 carbon, 0.5 to 1.0 silicon, up to 0.1 aluminum, 0 to 0.005 sulfur, and balance iron and incidental impurities. The steels exhibit suitable corrosion resistance, electrical contact resistance, and mechanical properties for high-corrosion applications such as use in bipolar plate materials for PEM fuel cells. The bipolar plates may comprise a solid plate of the steel, optionally coated with a highly electrically conductive material. Alternatively, the bipolar plates may comprise an economical substrate coated with the steel, optionally further coated with a highly electrically conductive material.

摘要： A fuel cell stack that includes a non-permeable shim plate positioned between a composite unipolar plate and a terminal plate at both ends of the stack, where the shim plate is made of a non-corrosive material, such as stainless steel, titanium or sealed graphite. Because the shim plate is non-permeable, it prevents cooling fluid that diffuses through the unipolar plate from contacting the terminal plate, which would otherwise corrode the terminal plate. The shim plate can be coated with a conductive material, such as gold, platinum, ruthenium oxide or mixtures thereof, to reduce its contact resistance.
