Xinhaisen's chemically etched bipolar plates deliver superior performance in fuel cells, electrolyzers, and flow batteries. Our photochemical etching technology enables complex micro-flow patterns with unmatched precision, optimizing gas/liquid distribution while minimizing pressure drop. These plates are critical for improving energy efficiency in hydrogen applications.
Bipolar Plates Features
Ultra-Precise Micro-Channels: Achieves exact channel dimensions, depths, and land widths with exceptional uniformity for optimal fluid dynamics and electrical contact.
Stress & Burr-Free: The non-contact etching process ensures no mechanical stress, no deformation, and absolutely smooth channel walls, critical for sealing and stack integrity.
Design Agility: Effortlessly accommodates complex, multi-zone flow field patterns (serpentine, parallel, pin-type) and custom port designs without expensive hard tooling.
Material Versatility: Processes a wide range of conductive metals, including titanium, stainless steel (316L), aluminum, and coated substrates.
High Throughput & Scalability: Perfectly suited for both rapid prototyping (days) and cost-effective, high-volume production.
Excellent Surface Finish: Provides an ideal, consistent surface for subsequent critical coatings, enhancing performance and longevity.

PEM Fuel Cells: For automotive, stationary power, backup systems, and portable power devices.
PEM Electrolyzers: For green hydrogen production.
Redox Flow Batteries: As electrode plates or current collectors.
Research & Development: For testing novel flow field designs and materials with fast turnaround.
Q: Why is photochemical etching better than stamping for bipolar plates?
A: Etching produces no stamping-induced stress, warping, or burrs that compromise sealing. It allows for more complex, finer channels, eliminates high-cost hard tooling, and enables effortless, low-cost design changes.
Q: Can you produce plates with different flow field patterns on each side?
A: Yes, our process can easily create anode and cathode patterns with different geometries on a single plate (bipolar design) with high alignment accuracy.
Q: Do you provide coated bipolar plates?
A: We specialize in the precision etching of the base plates. We can supply uncoated, cleaned plates ready for coating, or work seamlessly with your specified coating partners as part of a integrated supply chain.
Q: What is your capability for large-format plates?
A: Our equipment can handle large sheet sizes. Please consult our engineering team with your specific active area dimensions and thickness requirements for feasibility.
