The invention provides a process for the preparation of low-density multicomponent graphite composite bipolar plate for fuel cell applications. The molded plates were fabricated using different particle size of expanded graphite, chopped carbon fiber, carbon nanotubes and thermosetting polymer as binder. The Expanded Graphite (EG), which is vermiform in shape, offers high surface area and therefore good affinity to polymers. The multicomponent graphite composite bipolar plates possess high electrical and mechanical properties.
