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.
摘要翻译：一种燃料电池堆，其包括位于堆叠两端的复合单极板和端子板之间的不可渗透垫片，垫片由非腐蚀性材料制成，例如不锈钢，钛或密封石墨。因为垫板是不可渗透的，所以它防止通过单极板扩散的冷却液与接线板接触，否则会使端子板腐蚀。垫板可以涂覆有导电材料，例如金，铂，氧化钌或其混合物，以降低其接触电阻。

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.
