Abstract
The graphitized composite article of the present invention is formed by embedding carbon fiber felt in a matrix of a carbon filler; a thermosetting resin and a solvent; curing the composite article; then, carbonizing and graphitizing the cured composite article to form the graphitized composite article for use as a separator plate capable of substantially inhibiting mixing of hydrogen and oxygen and/or the loss of electrolyte within a fuel cell stack. The graphitized composite article may be a graphitized laminate.
