In this episode of The Zero Emission Zone, we break down the science behind balancing platinum-carbon (Pt/C) ratios and humidity levels to supercharge Proton Exchange Membrane Fuel Cells (PEMFCs). We’ll explore how researchers are enhancing performance and oxygen distribution by tweaking these key variables in the graded ionomer catalyst layer. Tune in to discover how small changes in humidity and Pt/C ratios can lead to big gains in fuel cell efficiency and durability, bringing us closer to a cleaner, more sustainable energy future.
