Titanium Etching Bipolar Plates With Micro Flow Field For Fuel Cells

Titanium Etching Bipolar Plates With Micro Flow Field For Fuel Cells

The titanium bipolar plate adopts titanium etching technology, which has the characteristics of lightweight, high strength, and corrosion resistance. This etching technology not only retains the original advantages of titanium material, but also ensures that the product surface is smooth like a mirror, with precise shape, high durability and stability.

Specifications of Titanium Bipolar Plates for Fuel Cell

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.

Xinhaisen can custom photo etch bipolar plates in various shapes. Below are some examples we have produced for reference

The production process of of Titanium Bipolar Plates for Fuel Cells

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.
