uniform thickness including corners

Feature 2:Stable Height of Flow Channel

Bipolar plate which has 5mm-height of flow channel has less than 20μm variety of height.


Feature 3 :Exceptional Flatness

350mm-size bipolar plate has less than 3mm flatness.

Example of design of metal bipolar plate flow channel

We have the forming database based on many experiences. We are able to propose the optimized cross-section shape of flow channel depending on material property to supply high-quality metal bipolar plates.
Please refer to the example of graph bellow which shows formable area of SS316L and pure Ti based on our database.

Width of flat area & Angle of flow channel

◆Relationship between Pitch and Height of Flow Channel (Material Thickness 0.1mm)

Angle of flow Channel : 13.5°

Angle of flow Channel : 5°
