Graphite polar plate with hydrophobic layer

The utility model discloses a graphite polar plate with hydrophobic layers, which relates to the technical field of fuel cells and comprises a polar plate body, first hydrophobic layers and second hydrophobic layers, the surface of the polar plate body is provided with a plurality of runner grooves, and the first hydrophobic layers and the second hydrophobic layers are arranged in the runner grooves at intervals. The height of the second hydrophobic layer is larger than that of the first hydrophobic layer and smaller than that of the flow channel groove. According to the utility model, the drainage performance in the flow channel groove is effectively improved by arranging the drainage layer, so that liquid water in the flow channel groove of the graphite polar plate can be timely purged and cleaned, liquid water residue is avoided, the purge stoichiometric ratio is reduced, and the parasitic power consumption of an air compressor is reduced. Because the height difference exists between the first hydrophobic
