The invention relates to a fuel cell graphite plate surface peel strength detection method, which comprises: S1, covering a graphite plate with an adhesive tape, and adhering the adhesive tape and the graphite plate by using a constant force; s2, fixing the graphite plate adhered with the adhesive tape in a material testing machine, and stripping the adhesive tape from the surface of the graphite plate by using a tensile fixture at a constant tensile speed under a constant force; s3, placing the stripped adhesive tape in a microscope for observation, and storing an image; and S4, analyzing the content of the graphite particles on the stripped adhesive tape by using image processing software so as to compare the surface stripping strength of the ink plate. Compared with the prior art, the method has the advantages of screening out polar plates with insufficient surface peel strength and large graphite powder falling amount to reduce pollution of a system end gas cavity and an anti-freezing ...

The invention relates to a gap bridge structure of a fluid inlet and outlet area of a graphite bipolar plate of a fuel cell. The gap bridge structure of the fluid inlet and outlet area of the graphite bipolar plate of the fuel cell comprises bridge piers and bridge surfaces, the bridge piers are connected with the bridge floor, and the bridge piers are located above the bridge floor; the deck includes an imprint reinforcement that is recessed with respect to an upper surface of the deck. And the impressing enhancing part is in a concave rhombus shape or a strip shape. Compared with the prior art, the gap bridge structure for the fluid inlet and outlet area of the graphite bipolar plate of the fuel cell, disclosed by the invention, can effectively improve the pressure bearing capacity of the gap bridge area of the graphite bipolar plate on the premise of meeting a certain flow resistance requirement by arranging the impressing enhancing part.
