Advantages of Titanium Etching Metallic Bipolar Plate
—————————
- Stress-free: Eliminates internal stresses and deformation caused by mechanical processes such as stamping, preserving the flatness of the sheet material.
- Burr-free: The etching process naturally forms smooth flow channel walls, eliminating the need for secondary deburring and ensuring sealing integrity.
- High precision: Capable of perfectly replicating design drawings, achieving exceptional dimensional consistency and repeatability.

The production process of photochemical machining titanium bipolar plates
—————————
1. Material selection (stainless steel/titanium)
2. Surface cleaning
3. Photoresist coating to define flow channel patterns
4. Exposing and Developing
5. Chemical etching to dissolve exposed areas
6. Post-processing (resist removal, residue neutralization)
7. Quality inspection
Precise control of etching parameters (time, temperature, concentration) ensures uniform channel geometry for optimized gas distribution, conductivity, and corrosion resistance while maintaining structural integrity. This method supports scalable, cost-efficient mass production.
