Etching creates precise flow channel patterns in bipolar plates, optimizing gas diffusion and reducing pressure drops. This subtractive method ensures uniform geometry to enhance flow efficiency and electrochemical performance while maintaining material conductivity. It enables corrosion-resistant materials (e.g., stainless steel/coated metals) and supports scalable production with balanced cost-durability for sustained fuel cell operation.
The production process of chemically etched bipolar plates
—————————
1. Material selection (stainless steel/titanium)
2. Surface cleaning
3. Photoresist coating to define flow channel patterns
4. Exposing and Developing
5. Chemical etching to dissolve exposed areas
6. Post-processing (resist removal, residue neutralization)
7. Quality inspection
Precise control of etching parameters (time, temperature, concentration) ensures uniform channel geometry for optimized gas distribution, conductivity, and corrosion resistance while maintaining structural integrity. This method supports scalable, cost-efficient mass production.
