FLEXIBLE GRAPHITE COMPOSITE FOR USE IN THE FORM OF A FUEL CELL FLOW FIELD PLATE

摘要

Flexible graphite sheet having embedded ceramic fibers extending from its surfaces into the sheet to increase the permeability of the sheet to resin which is grooved by mechanical deformation into a shape useful as a flow field plate in fuel cells, having a thin sheet of flexible graphite affixed to the grooved sheet to provide support therefor.
