Molding of fluid permeable flexible graphite components for fuel cells

摘要

Materials and methods of manufacturing materials useful in the forming of fuel cell components are disclosed. A mass of expanded particles of natural graphite is molded into a foraminous sheet having parallel opposed first and second surfaces and having a plurality of transverse fluid channels passing through the sheet between the first and second parallel opposed surfaces. The particles of natural graphite may be either virgin particles, recycled particles or a blend thereof.
