(Hydrogen Fuel Cell Stack Production Process)
● Stacking: Initially, the lower end plate, current collector, and insulation plate are positioned on the assembly workbench. The MEA and BPP (including gaskets) are stacked sequentially until the required number is reached. Finally, the end plate with the media interface, current collector, and insulation plate are stacked on top.
● Compacting: Pressure is applied to compress the components (including the gaskets) to create a seal.
● Tensioning: Use tension bands or tie rods to ensure the stack is compressed and permanently fixed. This process is performed within a press. Tie band connections are secured using welding, connectors, clamps, or special-shaped bending structures.
● Leak Testing: Use pressure drop or flow testing to verify the stack's sealing performance. The test gas is introduced into the stack and leak testing equipment.
● Assembly of Other Accessories: Connect the battery's high-voltage output busbars to the current collectors. Install the stack into the housing. This also includes connections for all media inputs and outputs, sensors, and high-voltage cables.
The production line continues to operate in excellent condition, creating value for customers, which is highly praised and recognized, and Suntech's service is highly commended.
