Abstract
The invention relates to the field of fuel cells, and particularly discloses a graphite bipolar plate for a fuel cell and a manufacturing process therefor. The manufacturing process for the graphite bipolar plate for the fuel cell comprises the following steps: S1, pre-pressing: pre-pressing exhaust lines on one surface or two surfaces of a graphite plate to obtain a prepressed bipolar plate; and S2, mold pressing: according to the design requirement of a flow channel, mold-pressing a flow channel on one surface or two surfaces of the prepressed bipolar plate after prepressing to prepare the double-grain graphite bipolar plate. The graphite bipolar plate for the fuel cell has the advantages of high conductivity and good mechanical property.
