Ultra-Thin Stainless Steel & Titanium Etched Bipolar Plates for PEM Electrolyzer Stack
Product Overview
Bipolar plates are critical parts in proton exchange membrane fuel cells (PEMFC) and electrolyzers. They distribute fuel and oxidant, conduct current, and remove heat. Xinhaisen uses high-precision chemical etching to produce lightweight, corrosion-resistant bipolar plates with complex flow field designs, ensuring consistent performance and durability.
Etching Process Steps
-
Material Preparation – Select stainless steel, titanium, or other alloys (0.05–3.0mm thick).
-
Cleaning – Remove oil and contaminants for uniform etching.
-
Lamination – Apply dry film photoresist on both sides.
-
Exposure & Development – Transfer flow field pattern using high-resolution photo tools.
-
Etching – Spray etch both sides simultaneously for burr-free, stress-free channels.
-
Stripping – Remove photoresist.
-
Inspection – Automated optical measurement of channel depth, width, and uniformity.
Product Features
-
Complex flow fields – Micro-channels from 0.1mm width.
-
High uniformity – ±0.05mm channel depth/width accuracy.
-
Burr-free & stress-free – No mechanical deformation.
-
Material versatility – SS304, SS316, titanium, nickel alloys.
-
Corrosion resistant – Smooth etched surface enhances coating adhesion.
-
Low contact resistance – Ideal for high-efficiency fuel cells.

FAQ
- Q1: What materials do you recommend for corrosive environments?
A: Titanium and SS316 offer excellent corrosion resistance for long-life fuel cells. - Q2: Can you produce both anode and cathode plates?
A: Yes. We etch both sides simultaneously with different patterns if required. - Q3: What is the typical lead time for custom bipolar plates?
A: Sample tooling: 5–7 days. Production: 7–15 days after approval. - Q4: Do you offer post-etching services?
A: Yes – cleaning, passivation, flatness correction, and surface coating (on request). - Q5: What’s the minimum order quantity?
A: Samples or mass production MOQ can be negotiated.
