Product Description
Bipolar Plates (BPPs) are critical core components in fuel cells and electrolyzers. These multifunctional elements distribute reaction gases (hydrogen and oxygen), collect generated current, remove heat, and provide structural support to the stack. Their performance directly impacts the power output, efficiency, and lifespan of energy systems.
Manufacturing Process
We specialize in producing metallic bipolar plates using advanced chemical etching technology. This process is ideal for creating complex, precise flow field patterns required for optimal fluid dynamics and electrical contact. Photolithography ensures accurate pattern transfer onto metal sheets, guaranteeing high fidelity and consistency.
Key Features
- High Precision & Complexity: Achieve intricate flow field designs with fine channels and micro-features
- Excellent Flatness & Uniformity: Ensures tight sealing and low contact resistance within the stack
- No Burrs or Stress: Etching process produces smooth channels without mechanical stress or burrs
- Material Versatility: Process various conductive metals including stainless steel, titanium, and aluminum
- Rapid Prototyping & Mass Production: Flexible solutions from quick-turn prototypes to high-volume orders
