Xinhsen'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
