Etching is crucial for creating precise flow channels in bipolar plates, optimizing gas distribution and reducing pressure drops. This process ensures uniform channel geometry, improving flow efficiency and electrochemical performance. It works with corrosion-resistant materials like stainless steel or coated metals while maintaining conductivity. Advanced etching techniques offer high reproducibility and scalability, balancing cost and durability to enhance fuel cell longevity and power density.
