Fuel Cell Bipolar Plates: High-Performance Etching Solutions
What is a Fuel Cell Bipolar Plates?
A fuel cell bipolar plate is a critical component in fuel cell stacks, responsible for distributing reactant gases (hydrogen and oxygen), collecting electrical current, removing heat, and providing structural support. Its precision design directly impacts fuel cell efficiency, durability, and power output.
Fuel Cell Bipolar Plates' Key Performance Features
Fuel Cell Bipolar Plates' Materials
We specialize in etching stainless steel, titanium, nickel alloys, and aluminum for fuel cell applications.
Why These Materials?
1. Stainless Steel & Titanium:
♦ Exceptional corrosion resistance in acidic/alkaline conditions.
♦ High mechanical strength for long-term durability.
♦ Superior thermal conductivity for heat management.
2. Nickel Alloys:
♦ Ideal for high-temperature fuel cells (e.g., SOFCs).
♦ Combines conductivity with oxidation resistance.
3. Aluminum:
♦ Lightweight alternative for portable fuel cell systems.
♦ Cost-effective without compromising performance.
Why Chemical Etching for Bipolar Plates?
Chemical etching outperforms traditional machining methods for flow field plates:
Complex Geometries: Achieve intricate microchannel patterns without tool wear.
Burr-Free Edges: Eliminate post-processing and ensure leak-proof seals.
Material Integrity: No heat-affected zones or mechanical stress.
Scalability: Cost-effective for both prototypes and mass production.
Thin Material Handling: Precision etching down to 0.02mm thickness
What is Chemical Etching?
Chemical etching is a subtractive manufacturing process that uses controlled chemical reactions to selectively remove material, creating precise, complex parts.
Fuel Cell Bipolar Plates' Etching Process Steps:
- Material Prep: Clean and degrease metal sheets.
- Photoresist Coating: Apply UV-sensitive resist.
- Exposure: Transfer flow field design via photomask.
- Development: Remove unexposed resist to reveal etching areas.
- Etching: Immerse in etchant to dissolve unprotected metal.
- Strip & Clean: Remove residual resist and polish.
- QC Inspection: Validate dimensions, conductivity, and surface finish.
