Precision Etching Metallic Bipolar Plates for Fuel Cell Electrolyzers

Precision Etching Metallic Bipolar Plates for Fuel Cell Electrolyzers

Bipolar Plates Overview

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 Key Advantages

·Ultra-thin designs (0.5-3.0mm) with high structural integrity
·Corrosion-resistant surfaces for acidic/alkaline environments
·Custom flow field patterns (serpentine, interdigitated, biomimetic)
·Zero mechanical stress vs. stamped/laser-cut alternatives
·Rapid prototyping → mass production transition
