Core Features of Customizable Titanium Bipolar Plates

—————————

• Advanced Manufacturing Process: Employing photochemical etching technology. This non-traditional, stress-free machining method chemically dissolves metal with precision, enabling the production of exceptionally intricate and precise flow channel patterns free from burrs or deformation.

• Superior Material: Utilises titanium as the base material. Titanium offers exceptional corrosion resistance, high specific strength, and lightweight properties, making it ideal for prolonged use in demanding fuel cell or electrolyser environments.

• Highly Customisable: This process is well-suited for prototype development and small-batch production, enabling rapid, low-cost design modifications. Customers may customise flow channel geometry, layout, port positioning, and other specifications as required.

• Extensive thickness range: Capable of processing titanium plates from 0.5mm to 2mm thick, offering flexibility for diverse application requirements such as power density and structural strength specifications.

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.
