Descrizione del prodotto
Chemical Etched Metal Bipolar Plates for Japanese Fuel Cells & Redox Flow Batteries
Product Overview
Shenzhen Xinhaisen Technology Limited specializes in high-precision chemical etching for metal parts. Our etched bipolar plates are manufactured using advanced photochemical machining, delivering superior flatness, micro-channel precision, and design flexibility for hydrogen fuel cells, redox flow batteries, and PEM electrolyzers.
With etching capabilities on materials from 0.5mm to 3.0mm thick, we produce bipolar plates with intricate flow fields, minimal burrs, and no thermal stress.
Etching Process
-
Material preparation – Stainless steel, titanium, or other alloys.
-
Cleaning & lamination – Double-sided photoresist coating.
-
UV exposure – Using high-precision photo-tools to define flow channels.
-
Developing – Removing unexposed resist.
-
Spray etching – Simultaneous double-sided etching for uniform channels.
-
Stripping & cleaning – Resist removal and deionized water rinse.
-
Inspection – 2.5D measurement, flatness test, and channel depth check.
Product Features
-
High uniformity: ±0.05mm tolerance across the entire plate.
-
No burrs or heat distortion: Etching preserves material properties.
-
Complex geometries: Any parallel or pin-type flow field design.
-
Material versatility: SUS304, SUS316L, titanium, nickel, and alloys.
-
Thin to thick plates: 0.5mm to 3.0mm.
-
Fast prototyping to mass production: No hard tooling costs.

FAQ
- Q: What materials do you recommend for bipolar plates?
A: For PEM fuel cells, SUS316L or titanium (Grade 1 or 2) is common. We help you select based on corrosion resistance, conductivity, and cost. - Q: Can you make double-sided flow channels?
A: Yes. Our double-sided etching creates different flow fields on the anode and cathode sides without extra tooling. - Q: Do you provide surface coating (e.g., gold, carbon)?
A: We focus on etching. However, we partner with certified coating suppliers – please inquire. - Q: What is your typical tolerance for channel depth?
A: ±10% of material thickness, but we can achieve ±0.02mm with process control. - Q: How do I request a quote?
A: Send your CAD (DXF/DWG) and material/thickness requirements to our sales team.
