Etching plays a critical role in manufacturing bipolar plate flow channels by enabling precise, intricate patterns that optimize gas distribution and minimize pressure drops. This subtractive process ensures uniform channel geometry, enhancing reactant flow efficiency and electrochemical performance. It accommodates corrosion-resistant materials like stainless steel or coated metals while preserving conductivity. Advanced etching techniques achieve high reproducibility and scalability, balancing cost-efficiency with durability—key for maintaining fuel cell longevity and power density under operational stresses.

The production process of of Titanium Bipolar Plates for Fuel Cell:

1) Material selection (stainless steel/titanium);

2) Surface cleaning;

3) Photoresist coating and UV masking 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.
