    • This disclosure relates to a method for making a polymeric article mold, a method for making a polymeric article with that mold, and improved surface topography features for a polymeric article. A prototype article is formed and then coated with a thin conductive layer. The coated prototype article is then electroformed until nickel plated to a sufficient depth to define a nickel plating tool. After the prototype article has been removed from the mold face of the nickel tool, the tool can be used as a mold for forming finished polymeric articles which replicate the original prototype article. The use of fine topography features such as a dense upstanding stem array on the surface of the prototype article facilitates accurate and complete electroforming by increased surface area presentation. The disclosure also presents improvements to microreplicated surface structures such as stem arrays. The improvements include the formation on a stem array having separate zones of stems of differing heights, and the formation of directional microreplicated features (e.g., stems) which are oriented and shaped to promote or restrict frictional interaction in one or more particular directions.
    • 本公开涉及制备聚合物制品模具的方法,制备具有该模具的聚合物制品的方法以及用于聚合物制品的改进的表面形貌特征。 形成原型制品,然后涂覆有薄导电层。 然后将涂覆的原型制品电铸成直到镀镍至足够的深度以限定镀镍工具。 原型制品已经从镍工具的模具表面上移除后,该工具可以用作复制原始原型制品的成品聚合物制品的模具。 使用精细的地形特征,例如原型制品表面上密集的直立杆阵列,可以通过增加表面积来实现精确和完整的电铸。 本公开还提出了微复制表面结构如茎阵列的改进。 改进包括在具有不同高度的茎的不同区域的茎阵列上的形成,以及定向微复制特征(例如茎)的形成,其定向和成形以促进或限制在一个或多个特定方向上的摩擦相互作用。

    • An article bearing a flow field such as a distribution plate for use in a fuel cell is provided. The active portion of the article, i.e., the portion of the article bearing the flow field, comprises at least two subsections; a first central subsection and a second peripheral subsection; wherein channels within the first subsection have a cross-sectional profile that differs from that of channels within the second subsection. Typically, channels of the first subsection have lesser depth, greater draft or greater ratio of draft to depth. In addition, an article bearing a flow field is provided where the flow field comprises at least two channel segments which differ in draft. In addition, an article bearing a flow field is provided where the flow field comprises at least one channel segment comprising first and second channel walls which differ in draft.
