AI Technical Summary
Existing fuel cell stacks require frequent adjustments to the number of shims during assembly and maintenance to maintain compressive force, resulting in inconvenient operation and low efficiency. Furthermore, the compressive force decreases after the core structure ages, affecting performance and sealing.
A clamping device is adopted, including a movable wedge, a fixed wedge, and an adjustment component. The movable wedge is driven to move along the inclined surface of the fixed wedge by the adjustment component, thereby adjusting the distance between the end plate and the insulating plate, thus adjusting the compressive force on the reactor core, and automatically compensating for the loss of compressive force by the first elastic element.
It enables convenient assembly and maintenance of fuel cell stacks, reduces the number of maintenance operations, improves the reliability and stability of core compression adjustment operations, extends maintenance intervals, and reduces labor costs.
