Descripción del Producto
Custom Etched Metal Bipolar Plates for Japanese Fuel Cell & Battery Stacks
Product Overview
Xinhaisen’s precision-etched bipolar plates are key parts for proton exchange membrane fuel cells (PEMFC) and electrolyzers. Using advanced chemical etching, we produce ultra-flat, corrosion-resistant plates with complex flow field designs. Our process ensures burr-free, stress-free plates ideal for efficient gas distribution and current collection.
What Is Chemical Etching?
Chemical etching (also known as photochemical etching) is a subtractive manufacturing process that uses controlled chemical solutions to dissolve metal through photoresist patterns. Unlike stamping or machining, etching:
-
Leaves no burrs or heat-affected zones
-
Does not change metal properties
-
Allows rapid prototyping without tooling costs
-
Handles complex, fine features with high repeatability
Product Features
-
High precision – Minimum line width down to 0.015mm, accuracy up to ±0.01mm
-
Ultra-thin capability – From 0.5mm to 3.0mm thickness
-
Custom flow field designs – Straight, interdigitated, or pin-type channels
-
Material options – Stainless steel (304, 316L), titanium, nickel alloys
-
Burr-free & flat – No secondary deburring needed
-
Corrosion resistant – Ideal for acidic fuel cell environment
-
Cost-effective for medium to high volumes – No expensive hard tooling

Frequently Asked Questions (FAQ)
- Q: Can you produce bipolar plates with custom flow field patterns?
A: Yes. We work from your CAD or Gerber files. Any flow field geometry is possible. - Q: Is there any burr or deformation after etching?
A: No. Chemical etching produces burr-free, stress-free plates without mechanical deformation. - Q: What thickness do you recommend for PEMFC bipolar plates?
A: Typically 0.5mm – 3.0mm for stainless steel. We can advise based on your application. - Q: Do you offer coating or surface treatment?
A: We mainly provide bare etched plates, but can coordinate with partners for conductive or anti-corrosion coatings. - Q: What is your MOQ (Minimum Order Quantity)?
A: No fixed MOQ. We welcome prototypes (even 10–20 pieces) and large production orders.
