Abstract
An electrochemical cell separator plate formed from a composition of carbonizable resin, coke, and graphite particles, and methods of making and using the same. The separator plate has an improved balance of properties such as flexural modulus. The plates are formed by molding a composition of carbonizable resin, coke, and graphite particles, surface grinding the plate and then carbonizing and graphitizing the plate. The composition comprises about 40% to about 60% of carbonizable resin and about 60% to about 40% of a coke-graphite mixture. The coke-graphite mixture comprises about 30% to about 90% of coke particles and about 70% to about 10% of graphite particles. These separator plates may be used in, for example, fuel cells.
