In this episode of The Zero Emission Zone, we explore the impact of cation contaminants on proton exchange membrane (PEM) water electrolysis and how these impurities degrade performance over time. Drawing insights from the latest research, we discuss innovative methods to recover from contamination, including current-driven recovery techniques that show promise in restoring efficiency. Tune in to discover how cleaner hydrogen production can be achieved by mitigating the effects of common contaminants, like sodium and calcium, found in tap water.
