CARBONACEOUS COATINGS ON FLEXIBLE GRAPHITE MATERIALS

摘要

A flexible graphite sheet (34, 30) having a hydrophobic binder and a carbonaceous material adhered thereto is disclosed. The flexible graphite sheet (34, 30) may be used as an electrode or a gas diffusion layer in a fue l cell (10), such as a proton exchange membrane (12) fuel cell (10). Electrochemical systems having such a flexible graphite sheet (34, 30) and methods for making such flexible graphite sheets (34, 30) are also disclosed .
