Automotive Fuel Cells
Stationary Power Systems
Marine Fuel Cell
Aerospace Hydrogen Systems
What is Chemical Etching?
Chemical etching (also known as photochemical machining) is a subtractive manufacturing process that uses chemical solutions to dissolve metal precisely. Unlike traditional stamping or machining, etching creates burr-free, stress-free plates without mechanical force. This allows for complex micro-flow channel designs, tight tolerances, and rapid prototyping, making it ideal for the intricate structures required in bipolar plates.
Product Features
-
High Precision: Achieve micro-channel widths as fine as 0.015mm and uniform flow field depths with an accuracy of ±0.03mm.
-
Burr-Free & Stress-Free: Unlike mechanical punching, our process leaves no burrs or micro-cracks, ensuring the longevity and safety of the membrane electrode assembly (MEA).
-
Ultra-Thin Capabilities: Process metals as thin as 0.5mm, enabling lighter stacks and higher power density.
-
Complex Geometries: Capable of producing intricate flow field patterns (e.g., serpentine, parallel, pin-type) to suit specific gas diffusion requirements.
-
Material Versatility: Compatible with various metals including stainless steel (304, 316L), titanium, and other corrosion-resistant alloys.
-
Consistency: High-volume repeatability ensures that every plate in your stack performs identically.
-
High dimensional accuracy
Complex flow field patterns
Excellent corrosion resistance
Smooth burr-free surface
Thin metal processing
Low tooling cost
Fast prototyping
OEM & ODM support

FAQ
- Q: What materials do you recommend for bipolar plates?
A: We typically recommend Stainless Steel (316L) for its excellent corrosion resistance and cost-effectiveness, or Titanium for applications requiring higher strength-to-weight ratios. - Q: Can you achieve the tight tolerances required for sealing?
A: Yes. Our etching process maintains a uniformity of ±0.01mm, ensuring that the plates mate perfectly with gaskets to prevent gas leakage. - Q: Do you charge high tooling fees for custom designs?
A: No. One of the major benefits of chemical etching is the low tooling cost. We use digital tooling, allowing us to adjust flow field designs quickly without expensive physical molds. - Q: What is the lead time for a prototype?
A: Typically, prototypes can be delivered within 5 to 7 days after design confirmation. - Q: Can you handle large-scale production?
A: Absolutely. We are equipped to handle massive, high-volume orders while maintaining strict consistency across all plates.
