Engineering Development And Manufacturing

Zhizhen Co., Ltd. has independent intellectual property rights metal polar plates production lines, with the delivery ability of full process chain processing, which can provide OEM processing.
Shanghai Zhizhen manufacturing base covers an area of 5000 square meters, with a designed annual output of 500000 pairs. It has provided customers with approximately 4 million sets of metal polar plates products in total.The Suzhou Zhizhen Phase I manufacturing base covers an area of nearly 20000 square meters, with a designed annual output of 3.5 million pairs. After the completion of Phase II, the annual output will reach 10 million pairs.


Utilizing laser welding technology to fabricate the flow-through structure of the metal pole plates with the "two plates and three fields" conguration. Laser spot diameter ≤0.05mm, and the annual output reaches more than 10 million sets.

Spot diameter ≤0.05mm


Utilizing five-axis coordinated high-speed milling, incorporating process compensation solutions for various working conditions, and creating single-plate stamping die features with precision character-istics ≤2μm.

Feature accuracy ≤2μm


In order to get high conductivity, corrosion resistance, and high bonding nano coatings on the surface of Metal polar plate,Zhizhen has developed an UltraPVD vacuum coating system using a continuous deposition scheme to achieve metal deposition, with surface coating life of the electrode plate exceeds 20000 hours.

Life span >20000H


Employing high-precision, large-tonnage hydraulic presses to manufacture metal pole plates for fuel cells, achieving a precision-controlled micro-feature stamping process with accuracy within a range of ±10μm.

Precision control ±10μm
