In this episode of The Zero Emission Zone, we explore the challenges of protonic resistance in hydrocarbon-based cathodes for Proton Exchange Membrane (PEM) fuel cells under low humidity conditions. Learn how this research uncovers the origins of high resistance, its implications on performance, and innovative mitigation strategies. We discuss the potential of reducing cathode thickness and optimizing ionomer content to improve fuel cell efficiency, paving the way for more sustainable and cost-effective energy solutions. Tune in to hear how these advancements are pushing the boundaries of clean energy technology.
