Photo Chemical Etching Metal Bipolar Plates with Excellent Corrosion Resistance
What are Bipolar Plates?
Bipolar Plates (BPPs) are critical core components in fuel cells and electrolyzers. They serve as multifunctional elements that 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 the energy system.
Manufacturing Process
We specialize in producing metallic bipolar plates using advanced chemical etching. This process is ideal for creating the complex, precise flow field patterns required for optimal fluid dynamics and electrical contact. Photolithography ensures the pattern is accurately transferred onto the metal sheet before etching, guaranteeing high fidelity and consistency.
Bipolar Plates 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: The etching process produces smooth channels without mechanical stress or burrs, preventing damage to the Membrane Electrode Assembly (MEA).
·Material Versatility: We can process various conductive metals, including stainless steel, titanium, and aluminum.
·Rapid Prototyping & Mass Production: From quick-turn prototypes to high-volume orders, we offer flexible and scalable solutions.
