Abstract
Description
Technical Field
[0001] This invention relates to the field of anion exchange membrane fuel cell technology, specifically to an automated production press for anion exchange membrane fuel cell stacks. Background Technology
[0002] A battery stack is short for battery pack. Its structure generally includes a stack body and end plates on both sides of the stack body. The end plates have a ring of evenly distributed through holes around their circumference. After passing tension screws through the through holes in the two end plates, they are tightened using nuts. To ensure the stability of the clamping force between the end plates and the stack body, springs are usually installed below the nuts. Currently, the assembly of a battery stack mainly involves two processes: first, the stack is assembled on an assembly platform; then, the preliminarily assembled stack is transferred to a press station. The press clamps the end plates, and then the tension screws and nuts tighten and fix the end plates on both sides of the stack body. Finally, the pressure is released, and the springs are stressed.
[0003] Traditional anion exchange membrane stack presses mainly consist of a frame, a servo pressing system, positioning fixtures, a vision inspection module, conveyor rollers, and a control system. The frame supports the overall structure, the servo system provides precise pressure control, the positioning fixtures ensure alignment of components such as membrane electrodes and bipolar plates, the vision module monitors stacking accuracy in real time, the conveyor rollers enable automatic material flow, and the control system coordinates the operation of all components. In operation, parameters are first set through the control system. After the material is conveyed to the positioning area via the conveyor rollers, the vision system calibrates the position. The servo pressing system then applies pressure and stacks the material step-by-step according to the programmed sequence, monitoring pressure and alignment in real time. Once completed, the material is conveyed to the next process, achieving fully automated and precise stacking.
[0004] During the production and assembly of fuel cell stacks, various problems can easily arise due to the precision component processing, multi-step assembly, and stringent process requirements. These problems may directly affect the performance, lifespan, and safety of the fuel cell stack. The manufacturing quality of core components such as membrane electrode assemblies (MEAs), bipolar plates, and seals directly determines the assembly difficulty and final performance. If the anion exchange membrane in the MEA has pinholes, scratches, or edge damage, it can lead to direct mixing and leakage of hydrogen and oxygen after assembly, causing localized reactions to intensify, efficiency to decrease, and even safety hazards. Summary of the Invention
