Improving channel depth uniformity in rubber pad forming of metallic bipolar plates: An experimental and numerical approach

Key Points

• Enhancing channel depth uniformity leads to better fluid dynamics in bipolar plates, improving overall performance.
• A 30% increase in uniformity was achieved through a combination of experimental trials and numerical simulations.
• Experimental method and numerical simulations were employed to analyze rubber pad forming processes in metallic bipolar plate production.
• These findings may enable manufacturers to produce more efficient fuel cells, as uniform channels can enhance energy conversion efficiency.
