Problems solved by technology

[0002] Stress deformation of graphite bipolar plates after processing will lead to out-of-tolerance flatness, which seriously affects the contact resistance between bipolar plates and membrane electrodes, which directly leads to a decrease in the overall operating efficiency of the stack. This problem has always been a pain point in the industry and has not been effectively solved for many years. Therefore, a flatness correction device for graphite fuel cell plates is now proposed

Abstract

The invention relates to the technical field of graphite fuel cell panels, and discloses a graphite fuel cell panel flatness correction device which comprises a fixed base, a mounting plate is arranged over the fixed base, a correction assembly is arranged between the fixed base and the mounting plate, and the correction assembly comprises a lower device body, an upper device body, a placement groove and two positioning pins, a battery panel body is movably arranged in the placement groove in a sleeving manner, and a damping mechanism is arranged between the fixed base and the lower device body. According to the graphite fuel cell panel flatness correction device, through design of the correction assembly and the damping mechanism, the flatness of a bipolar plate can be controlled within 0.1 MM through the correction assembly in the device, so that the contact resistance of a product after assembly is reduced, the contact surface of a membrane electrode and the bipolar plate can be stressed more uniformly, the possibility that the membrane electrode is broken through is reduced, meanwhile, different pressure maintaining time and curved surface radians can be set according to different deformation amounts of the bipolar plate and different plate thicknesses.

Description

technical field [0001] The invention relates to the technical field of graphite fuel cell plates, in particular to a flatness correction device for graphite fuel cell plates. Background technique [0002] Stress deformation of graphite bipolar plates after processing will lead to out-of-tolerance flatness, which seriously affects the contact resistance between bipolar plates and membrane electrodes, which directly leads to a decrease in the overall operating efficiency of the stack. This problem has always been a pain point in the industry and has not been effectively solved for many years. Therefore, a flatness correction device for graphite fuel cell plates is now proposed. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a graphite fuel cell plate flatness correction device to solve the problems raised in the background art above. [0005] (2) Technical solutions [0...
