Fuel cell stack assembly hydraulic press is a special equipment manufactured by CNMM specially designed for hydrogen fuel cell stack assembly. Combined with the hydrogen fuel cell installation process, it uses specially designed tooling. After the body rotates, it relies on gravity to automatically position the bipolar plate and Membrane electrodes are easy to install and save time for lamination alignment. It adopts a three-beam and four-column structure, precision linear bearings, actuators and rotary actuators are servo electric cylinders, which can precisely control the force and displacement of press-fitting, and fine-tune the angle of rotation.
                                                                                                         
The assembly quality of the fuel cell stack has a very important influence on the performance of the battery. The stack assembly process will affect the internal resistance of the stack and the uneven distribution of fuel due to stress. The prior art mainly has the following deficiencies:
1. If each single cell is not well positioned during assembly, assembly misalignment is prone to occur, which will lead to uneven stress inside the fuel cell stack, affect the seal and even damage the membrane electrode assembly and the electrode plate.
2. The accumulation of positioning and processing tolerances will cause a slight distortion of the vertical force applied to the battery pack. This distortion will cause relative displacement between the MEA component and the bipolar plate, affect the size and shape of the common pipeline, and cause fluid between the cells Uneven distribution.
3. Poor controllability of applied pressure during packaging, which may easily cause damage to membrane electrodes and plates.
4. In the process of fastening with the screw, the screw will provide a certain compression force, and the pressure sensor cannot truly reflect the actual pressure inside the stack. At this time, if the stack is assembled by simply relying on the feedback control of the pressure sensor to apply a constant pressure to the stack , it is easy to cause damage to the membrane electrodes and plates.
