Precision Titanium Etching Bipolar Plates for Hydrogen Fuel Cell and Electrolyzer

Basic Information of Titanium Etching Bipolar Plates

Bipolar plates are main component of proton exchange membrane, alkaline and solod oxide fuel cells and electrolyzers. They are processed with complex flow fields or channels, when they stacked, it can distribute gas and air, also conduct electrical current from one cell to the next.

Features of Titanium Etching Bipolar Plates:

The bipolar plate is one of the core components in fuel cells and electrolyzers. It plays multiple roles in the stack, including conducting electricity, transporting gases and liquids, supporting the membrane electrode assembly (MEA), and managing heat and moisture. Its performance directly affects the efficiency, lifespan, and cost of fuel cells.

Application of Titanium Etching Bipolar Plates:

1. Hydrogen Fuel Cell: Automotive fuel cells, portable power supplies, and stationary power stations.
2. Water Electrolyzer: Green hydrogen production, PEM electrolyzers, and alkaline electrolyzers.
3. Energy Conversion Equipment: New energy storage systems such as metal-air batteries and flow batteries.

Photochemical Etching Bipolar Plate:

Traditional methods for manufacturing bipolar plates include stamping, laser processing, and CNC milling, but these methods have certain limitations when it comes to fine channels and ultra-thin sheets. Photochemical etching, however, has unique advantages in the manufacture of metal bipolar plates.

Why Choose Photochemical etching for manufacturing bipolar plate?

• High precision: capable of processing minimum channel widths of 0.1 mm with controllable depth, ensuring uniform fluid distribution.
• Stress-free and burr-free: avoids deformation and cracks caused by mechanical processing, ensuring airtightness.
• Suitable for ultra-thin metal sheets: capable of processing thicknesses ranging from 0.02 mm to 3.0 mm, with common bipolar plate thicknesses between 0.05–1.0mm.
• Flexible design: Enables complex double-sided semi-etched channels, suitable for customized R&D and rapid iteration.
• Cost advantage: Low mold costs, suitable for small to medium-volume production and prototype development.

Titanium Bipolar Plate Manufacturing Technology:

We have the capability to etch both curved and straight channels across full metal sheets, allowing for the seamless realization of intricate designs. Moreover, our process achieves precise depth control, guaranteeing accuracy and consistency in every project.
