Ultra-Thin Stainless Steel & Titanium Etched Bipolar Plates for PEM Electrolyzer Stack
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.
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.
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.
