Abstract

The invention discloses a fuel cell graphite bipolar plate production system. The system comprises a rack and also comprises automatic feeding, discharging and leveling equipment for a graphite polarplate, polar plate sealing ring dispensing and forming equipment, graphite polar plate sealing ring curing and forming equipment, graphite polar plate adhesive dispensing and forming equipment, bipolar plate bonding and curing equipment and a polar plate conveying mechanism which are arranged on the rack, wherein the automatic feeding, discharging and leveling equipment for the graphite polar plate is used for heating and leveling a cathode plate; the polar plate sealing ring dispensing forming equipment is used for carrying out sealing ring dispensing on an anode plate and the heated and leveled cathode plate; the graphite polar plate sealing ring curing and forming equipment is used for respectively drying and curing the anode plate and the cathode plate subjected to sealing ring dispensing; the graphite polar plate sealing ring curing and forming equipment is used for carrying out adhesive dispensing on the anode plate and the cathode plate after a sealing ring is cured and formed;and the bipolar plate bonding and curing equipment is used for bonding and curing the anode plate and the cathode plate subjected to adhesive dispensing to form a bipolar plate.

Description

technical field [0001] The invention relates to the field of fuel cell manufacturing, in particular to a fuel cell graphite bipolar plate production system, and more particularly to a hydrogen fuel cell graphite bipolar plate production system. Background technique [0002] The bipolar plate is the core component of the hydrogen fuel cell stack, and the graphite bipolar plate is bonded by the cathode plate and the anode plate of the unipolar plate. The difficulty in bonding bipolar plates at this stage is that the glue type is not easy to grasp, and the alignment accuracy of the cathode plate and the anode plate is not easy to control. In the process of gluing, it is easy to break the glue, and the high precision of the glue is difficult to control, which will easily cause poor sealing effect, and eventually lead to poor sealing performance of the entire stack system, which cannot meet the use requirements. In addition, if the alignment of the cathode plate and the anode pl...
