EFFICIENT FUEL CELL WATER TRANSPORT PLATES

摘要

A fuel cell separator or water transport plate is formed of graphite, carbon fibers and an inert thermosetting hydrophilic binder. The materials may be in powdered form, and plates, preferably channeled, are formed using heat and pressure. The hydrophilic properties of the plates may be improved by immersion in an oxidizing bath followed by water rinsing. The active materials included in the plate are substantially limited to graphite, carbon fibers and the binder, and no additional hyrophilic coatings, materials or any high temperature processes are involved.
