NOVELTY - High-strength graphite flow plate of fuel cell comprises 85-94 wt.% graphite powder, 5-15 wt.% crosslinking agent, and 0.5-4 wt.% conductive agent. USE - High-strength graphite fuel cell flow plate. ADVANTAGE - The high-strength graphite bipolar plate greatly improving the production efficiency of the pressed products and reducing the process cost. The use of rubber and silane coupling agents as toughening agents can significantly improve the strength of the bipolar plate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a high-strength graphite bipolar plate for preparing the graphite bipolar plate, which comprises mixing mixture, graphite powder, and crosslinking agent with the conductive agent to obtain a mixed powder, spreading the mixed powder on the mold, and hot pressing at a temperature of 120-150 degrees C and a pressure of 7-30 MPa for 1-5 minutes to obtain the high-strength graphite bipolar plate.
