Patent
·
OSTI ID:5478869
An electrochemical cell separator plate is described which consists of a molded, carbonized and graphitized product formed from a carbonizable and graphitizable molding composition wherein the improvement utilizing a carbonizable and graphitizable molding comprises composition which consists of: about 40 weight % to about 60 weight % of carbonizable resin; and about 60 weight % to about 40 weight % of a coke-graphite mixture; the coke particles having size less than 149 microns and the graphite particles having size less than 120 microns. The coke-graphite mixture comprising about 30 weight % to about 90 weight % of coke particles and about 70 weight % to about 10 weight % of graphite particles.
