Description
Ranadeb Ball's team probed how water controls ion flow inside a highly ordered polymer film for anion exchange, a part of fuel-cell systems. Standard films are messy in shape, which blurs the link between wetness, ion-water forces, and transport across time spans from femtoseconds to milliseconds.
Using dampness-based heat-ray scans, resistance checks, and small-scale simulations, the team found ions hopping in a sub-diffusive way. Wetness tuned how strongly ion pairs cling together, and thus the barrier to flow. A single-contact exchange process governed diffusion at every wetness level, hinting design rules for faster, more permeable membranes.
