Abstract

The invention relates to a stack pressing device for a fuel cell stack. The device comprises a base, columns arranged on the base in the vertical direction, a top plate arranged at the tops of the columns, an air cylinder assembly arranged on the top plate in the vertical direction, a positioning mechanism arranged on the base and located below the air cylinder assembly and a control mechanism electrically connected to the air cylinder assembly. Compared with the prior art, by selecting a pressing block with a suitable size and a suitable number of aluminum plates and utilizing air cylinder positioning holes and distance sensors to position an air cylinder and the aluminum plates respectively, it is ensured that the stack is accurate in position and uniform in stress, the situation that the assembly breakage happens to the stack in the stack pressing process is avoided, and the quality of the stack is ensured; stack pressing parameters are set through an operation panel, and then the device can automatically conduct the stack pressing process and is easy to operate, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and relates to a stacking device for fuel cell stacks. Background technique [0002] With the explosive development of the automotive hydrogen fuel cell industry, the demand for corresponding fuel cell stacks continues to increase. During the manufacturing process of the electric stack, it is necessary to press and assemble the electric stack, that is, to compress the stacked electric stacks so as to facilitate their fastening. However, due to the brittle materials such as graphite in the stack, if the stack is subjected to uneven force or the placement position is deviated during the stacking process, it is very easy to cause the components in the stack to break and affect the normal use of the stack. Contents of the invention [0003] The object of the present invention is to provide a stacking device for a fuel cell stack in order to overcome the above-mentioned defects in the prior art....
