Abstract
A process for manufacturing fuel cell plates including a continuous press, a sifter, a leveler and rollers for removing air from resin impregnated graphite. The sifted material is deposited on a heated lower press belt having an embossing pattern. The material is leveled to a predetermined height and squeezed to remove air. An upper belt, also having an embossing pattern, contacts the material and heat and pressure are applied in a reaction zone for a predetermined time period. The finished product is a relatively low cost fuel cell plate.
