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:
| Material Options | Aluminum, stainless steel, titanium, copper, nickel alloys |
| Thickness Range | 0.1 mm to 3.0 mm (customizable) |
| Tolerance | ±0.01 mm for high-precision flow field patterns |
| Channel Depth | 0.05 mm to 1.5 mm (adjustable based on fuel cell design) |
| Plate Dimensions | Up to 600 mm x 1800 mm (larger sizes available upon request) |
| Corrosion Resistance | Enhanced coatings (e.g., gold, platinum, or polymer) for PEM fuel cell environments. |
| Other Service | Plating, Stamping, Laser Cutting, etc. |
