Two ends of the conveying module 10 extend to the stacking station 101 and the turning press-fitting station 102 respectively, and are used for conveying the shell to the stacking station 101 and the turning press-fitting station 102.

The stacking module 20 is disposed at the stacking station 101, the stacking module 20 includes a transferring assembly 21 and a jacking assembly 22, the transferring assembly 21 is configured to obtain a bipolar plate and a membrane electrode, and stack the bipolar plate and the membrane electrode alternately on an end plate assembly of the housing along a first direction to form a stack, and the jacking assembly 22 is configured to drive the end plate assembly to move back and forth along the first direction. The overturning press-fitting module 30 is arranged at the overturning press-fitting station 102, the overturning press-fitting module 30 comprises an overturning press 31, and the overturning press 31 is used for press-fitting the stacked parts in the shell and overturning the shell.

It should be explained that, in the present embodiment, the first direction is a direction perpendicular to the paper surface in fig. 1, and is a vertical direction in the actual work flow.

Meanwhile, in the embodiment, the stack comprises a shell, a blind end plate, an end plate assembly, a single cell assembly and an air inlet end plate assembly, the blind end plate and the air inlet end plate assembly are located at two ends of the single cell assembly, the end plate assembly is located between the single cell assembly and the blind end plate, and the blind end plate and the air inlet end plate assembly are connected with the shell.

Because the air inlet end plate is installed after the stacking is finished, the shell can be firstly inverted, and when the stacking starts, the jacking assembly 22 jacks the end plate assembly to the top end of the shell, the end plate assembly can be driven to gradually descend through the jacking assembly 22 in the stacking process, so that the stacking height is ensured to be the same every time, the time consumption of stacking actions is reduced, the stacking precision is improved, and the stacking efficiency is improved.

In this embodiment, the bipolar plate and the membrane electrode are stacked in the housing, and the inlet end plate assembly and the blind end plate are manually assembled.

Moreover, the shell is inverted and then stacked, the bottom of the shell is provided with the end plate assembly, and the size of the end plate assembly is smaller than that of the air inlet end plate assembly, so that the end plate assembly can ascend and descend in the shell, and therefore when the bipolar plate and the membrane electrode are stacked in the shell, the end plate assembly can descend gradually, and time consumption of stacking actions is reduced.
