摘要： The present invention relates to a flexible graphite sheet having increased isotropic properties. More particularly, the present invention relates to a flexible graphite sheet formed from particles of expanded natural graphite formed from graphite flake sized no more than about 30% by weight +80 mesh prior to expansion. The resulting sheet of flexible graphite exhibits improved conductive and fluid sealing properties.

摘要： An improved method enables preparation of articles for a variety of applications, including embossing or otherwise shaping to form a variety of articles. A plurality of thin, preferably resin-impregnated, flexible graphite sheets are arranged to form zones in a composite material having a graded density or other characteristic. Variation of properties between zones in the stock material formed is useful for achieving a desired set of properties in the formation of articles such as those useful in electrochemical fuel cells and double-layer capacitors.

摘要： The invention relates to tubular fuel cells and methods of making such fuel cells. The inventive fuel cells include at least one fluid permeable structure having a plurality of perforations or channels. The perforations allow fluids, e.g., hydrogen or oxygen, to flow through the structure. The inventive methods include forming at least one perforated structure and forming the perforated structure into a tubular fuel cell or at least a potential component of a tubular fuel cell.
