Electrolyzer Flow Field Plates: Precision-Crafted for Optimal Performance
What are Electrolyzer Flow Field Plates?
Electrolyzer flow field plates are critical components in hydrogen production systems, designed to evenly distribute reactants (water/electrolytes) and efficiently collect reaction products (hydrogen/oxygen). These plates feature intricate micro-channel patterns that maximize surface contact and optimize electrochemical reactions.
Electrolyzer Flow Field Plates Key Product Features
Superior Corrosion Resistance (compatible with acidic/alkaline environments)
Exceptional Electrical Conductivity (＜0.05Ω·cm surface resistivity)
Precision Flow Channels (±0.02mm dimensional accuracy)
High Temperature Tolerance (up to 200°C continuous operation)
Ultra-Thin Profiles (0.1-3mm thickness options)
Electrolyzer Flow Field Plates Material Selection Expertise
We engineer electrolyzer flow field plates using advanced materials:
| Material | Key Advantages | Typical Applications |
| Titanium (Grade 1-5) | Extreme corrosion resistance, lightweight | PEM electrolyzers |
| 316L Stainless Steel | Cost-effective durability | Alkaline electrolyzers |
| Nickel Alloys | High-temperature stability | SOEC systems |
| Iron-Nickel (Invar) | Near-zero thermal expansion | Precision stack assemblies |
Material selection based on electrolyte chemistry, operating pressure (up to 70 bar), and hydrogen purity requirements.
Common Applications:
- PEM Water Electrolyzers
- Alkaline Electrolyzers
- Solid Oxide Electrolysis Cells (SOEC)
- Hydrogen Compression Systems
- Fuel Cell Stacks
Why choose Chemical Etching for Electrolyzer Flow Field Plates?
Our photochemical etching process delivers unmatched advantages:
✔️ Complex Geometry - Create 0.1mm wide channels with sharp 90° angles
✔️ Stress-Free Production - No mechanical deformation or heat-affected zones
✔️ Rapid Prototyping - 5-7 day lead time for functional samples
✔️ Cost Efficiency - No hard tooling required for design iterations
✔️ Burr-Free Edges - Maintain consistent flow characteristics
What is Chemical Etching?
Chemical etching is a subtractive manufacturing process that uses controlled chemical reactions to selectively remove material, creating precise, complex parts.
Our 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.
