Custom Etched Bipolar Plates PEM Fuel Cell Stack Components

Descriptions of Etched Bipolar Plate:

The bipolar plate distributes reactant gases, conducts electrons, and optimizes flow channels via corrosion-resistant materials (graphite/coated metals) for durable, cost-effective fuel cell performance.

Specifications of Etched Bipolar Plate:

Features of Etched Bipolar Plates:

1. Ultra-Precise Flow Field Patterns: Complex microchannels etched for optimal hydrogen/oxygen distribution and water removal.

2. Lightweight Design: Aluminum plates reduce stack weight, ideal for automotive and portable applications.

3. High Electrical Conductivity: Seamless current collection with minimal interfacial resistance.

4. Durability: Resistant to acidic PEM environments and thermal cycling.

5. Custom Geometry: Support serpentine, parallel, or hybrid flow field designs.

6. Scalability: Cost-effective for mass production with consistent quality.

Applications of Etched Bipolar Plates:

• Automotive: PEM fuel cells for hydrogen-powered vehicles.

• Aerospace: Lightweight energy solutions for drones and satellites.
