This 3T membrane electrode assembly (MEA) airtightness testing servo press is a high-precision integrated solution specifically designed for the encapsulation and testing of membrane electrodes—the core component of hydrogen fuel cells. It delivers a stable pressing force of up to 3 tons, ensuring uniform force distribution and zero slippage during the encapsulation process of MEA assemblies. Featuring fully closed-loop servo control and millisecond-level pressure feedback, the equipment controls the press-fitting process with micron-level precision. This perfectly prevents irreversible damage to the precious and fragile membrane electrode materials caused by pressure or displacement deviations.
PRODUCT DESCRIPTION
Its core value lies in integrating precision hot-press encapsulation with inline leak testing. Following encapsulation, the equipment immediately performs ultra-high-sensitivity non-destructive leak testing within a sealed chamber, precisely identifying minute leakage points to ensure absolute sealing integrity for every membrane electrode assembly. This not only achieves “zero-transfer” production from encapsulation to quality inspection—significantly boosting yield rates and efficiency—but also provides critical technological support for ensuring the performance and safety of hydrogen fuel cell stacks.
