The large-scale stack assembly servo hydraulic press is a core piece of equipment specifically designed for the mass production of high-quality hydrogen fuel cell stacks.
Through its high-precision servo control system, it applies extremely accurate pressure and displacement control during the stack assembly process, ensuring that each bipolar plate, membrane electrode assembly, and seal is tightly bonded under optimal mechanical conditions. This not only directly determines the stack's output performance and service life but also serves as a critical safeguard for achieving product consistency and high yield rates, propelling the fuel cell industry from laboratory research toward large-scale commercialization.
PRODUCT DESCRIPTION
Application Scenarios
1. Flow Battery Stacks: Assembly and compression of large-format stacks, such as Vanadium Flow Batteries (VFBs) and Zinc-Bromine batteries.
2. Fuel Cell Stacks: Pre-assembly of Proton Exchange Membrane Fuel Cells (PEMFC) before leak testing.
3. Research Institutions: Process development and material research for various new stack structures and designs.
Core Advantages
1. Ultra-High Precision Displacement and Pressure Control
Full closed-loop servo drive paired with high-precision sensors achieves micron-level repeatability positioning accuracy and pressure control accuracy within ±1%, ensuring uniform end-face pressure across every cell in the stack and effectively preventing cracking of brittle bipolar plates.
2. Multi-Point Pressure Equalization Technology
Equipped with a self-leveling/floating pressure head that automatically adjusts the angle during the pressing process, eliminating eccentric loads during large-area stack assembly. This ensures uniform pressure across the entire surface, preventing damage caused by localized stress concentrations.
3. Intelligent Process Curve Storage
Features a built-in PLC and touch-screen industrial PC capable of storing hundreds of process recipes. It supports multi-stage speed and pressure-displacement/time modes, precisely matching the entire stack assembly process including positioning, degassing, and final compression.
4. High Efficiency, Energy Saving, and Cleanliness
The servo system consumes energy only during the pressing operation, achieving comprehensive energy savings of 30%-50%. It operates with low noise, requires no hydraulic oil, meets cleanroom workshop standards, and completely eliminates the risk of oil leakage.
