In this episode, we explore a groundbreaking study on how engineered cracks in the catalyst layers of Proton Exchange Membrane Fuel Cells (PEMFCs) could boost their durability and performance. Learn how these cracks, usually considered a flaw, can actually enhance oxygen transport and improve performance after stress testing. We dive into the science behind crack morphology, its role in durability, and what this could mean for the future of clean energy, particularly in heavy-duty vehicles. Tune in for a fascinating look at the unexpected benefits of cracking under pressure!
