Paragraph starter
This research explored the application of biomimetic design, specifically drawing inspiration from Murray's Law of branching, to optimize the flow field of a Proton Exchange Membrane (PEM) fuel cell. The study found that while the biomimetic design offered reduced pressure drop, it also presented challenges with flooding. The findings suggest that such designs could be more effective in high-temperature fuel cells where water management is inherently different, highlighting the importance of considering the operational context when adapting natural principles.
