Product Description

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.


    


            1. Excellent Corrosion Resistance

               Titanium offers outstanding resistance against acids, alkalis, and humid environments, making it

                ideal for PEM fuel cells and water electrolyzers, where long-term stability is critical.


            2. Lightweight with High Strength

               Compared to stainless steel and graphite, titanium provides a high strength-to-weight ratio, reducing

               stack weight while maintaining structural integrity. This is especially valuable in automotive and

               aerospace fuel cell applications.


            3. Precision Micro-Channel Design

               Through chemical etching, flow channels as small as 100 μm can be created with high dimensional

               accuracy. This ensures uniform reactant distribution and improves mass transfer efficiency inside the

               cell.


            4. Thin and Compact

               Titanium bipolar plates can be etched down to 0.05–2.0 mm thickness, achieving compact and

               lightweight stacks without compromising performance.


            5. Stress-Free and Burr-Free

               Unlike stamping or laser cutting, etching does not introduce mechanical stress, cracks, or burrs. The

               smooth channel surfaces improve sealing performance and reduce energy losses.


            6. Compatibility with Coatings

               Etched titanium plates can be further enhanced with surface coatings (e.g., gold, carbon, or

               conductive layers) to improve conductivity and reduce interfacial contact resistance (ICR).

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.


      Etching Dual-Depth Channels                                                    Surface Coated                                                 Laser Cutting

  We can etch different depths of                                                 For stainless steel materials,                               For metal sheets thicker
