Description

Chemical Etching Bipolar Plates for Fuel Cell with High Corrosion Resistance


Bipolar Plates Overview

Xinhaisen Technology specializes in manufacturing high-performance chemically etched bipolar plates for fuel cells, flow batteries, and other electrochemical applications. Our precision etching process enables complex flow field patterns with exceptional dimensional accuracy and surface quality.

Bipolar Plates Key Features

  • Complex, Burr-Free Channels: Creates intricate, multi-depth flow field designs with smooth, burr-free surfaces for optimal gas flow and water management.

  • High Precision & Consistency: Excellent uniformity across the entire plate and from plate to plate (±0.03mm), ensuring consistent fuel cell stack performance.

  • Material Versatility: Can process various corrosion-resistant conductive metals, including 316L stainless steel, titanium, and aluminum.

  • Thin & Lightweight: Capable of producing very thin plates (from 0.05mm), contributing to higher power density stacks.

  • Rapid Prototyping & Scale-Up: No hard tooling required for design iterations, enabling fast development cycles and seamless transition to volume production.
