After the bipolar plate 26 is cured, the bipolar plate 26 may be transported to a next process by a first layer-changing singulation mechanism 52. For example, the first curing oven 51 may adopt a "high temperature and high humidity curing oven + five layers of storage chains" to implement the buffer storage of the bipolar plate 26 and the wet heat curing of the glue. The first layer-changing separating mechanism 52 adopts a servo motor and ball screw structure to realize layer-changing buffer storage of the bipolar plate 26, and the number of the solidified layers 511 can be adjusted according to the production rhythm.
