▎ 摘　　要

NOVELTY - A carbon-based composite conductive paste comprises a conductive carbon material, a resin binder, and a resin curing agent. USE - The carbon-based composite conductive paste is useful for preparing graphite electrode plate (claimed) used for proton exchange membrane fuel cell used in traffic transportation application. ADVANTAGE - The carbon-based composite conductive paste: has excellent corrosion resistance; is low in cost, easy to produce, and suitable for mass production; adopts graphite bipolar plate, which is used to have a rich conductive network, and controls carbon materials with different particle size ranges, which is good for forming a curing center in the graphite plate, enhancing the gas and liquid barrier properties of the electrode plate, and improving the yield of the product; and utilizes resin binder, which helps to form continuous conduction network and improves electrical conductivity and thermal conductivity of the electrode plate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of a graphite electrode plate.
