In this episode of The Zero Emission Zone, we dive into the unique challenges faced by proton exchange membrane fuel cells (PEMFCs) in marine environments. This research highlights how exposure to sodium chloride, at concentrations similar to ocean air, can affect PEMFC durability. We explore the mechanics of salt particle buildup, the impact on cell performance, and why these effects are mostly reversible. Tune in to learn how this technology is adapting to salt-rich environments and the innovations needed to ensure sustainable, long-term use in maritime applications.
