Photo Chemical Nickel Etching Bipolar Plate with 0.5-3mm Thickness

What is Nickel Etching?

Nickel etching is a specialized photochemical machining process that selectively removes nickel or nickel-alloy material to produce precise, burr-free metal parts. It is ideal for creating thin, complex fluidic geometries with exacting tolerances for electrochemical applications.

Bipolar Plate Overview

Our chemically etched nickel bipolar plates (BPPs) are engineered for demanding applications in hydrogen fuel cells, flow batteries, and electrolyzers. Manufactured from corrosion-resistant nickel alloys, they feature precisely formed flow fields, gas channels, and sealing lands that optimize fluid distribution, thermal management, and electrical conductivity.

Bipolar Plate Features

• Precision Flow Channels: Uniform, repeatable channel geometries ensure consistent fluid/gas distribution.

• Corrosion-Resistant: Nickel material offers excellent durability in harsh electrochemical environments.

• Burr-Free & Smooth: No mechanical stress ensures clean edges and channels, preventing blockages.

• Design Flexibility: Easy customization of channel depth, width, and pattern without hard tooling.

• High Conductivity: Maintains excellent electrical performance across the plate surface.
