Organizers: Iryna Zenyuk (Tufts University), Svitlana Pylypenko (Colorado School of Mines).

Understanding charge transport in porous media subjected to real operating condition environment is critical for advancing energy-conversion and -storage technologies, such as fuel-cells, electrolyzers and redox flow-batteries. Ion transport processes in the porous reactive components in these devices rely on local solid-state electrolyte distribution, and other relevant porous material structural metrics, such as porosity, tortuosity, local wettability and pore-size distribution. In many instances, due to size-exclusion electrolyte is present only in macro-pores, whereas ion-conduction in micro- and meso-pores of these morphologically heterogeneous materials is not well understood. At nano-scale there is need for understanding ionomer interfaces with adsorbed water films and surface-mediated transport phenomena. This symposium will address critical progress in development and application of novel characterization techniques to further the understanding of interplay between porous media structure and ion transport. In-situ and in-operando techniques for probing local transport phenomena in fuel-cells, electrolyzers, and redox flow-batteries will be discussed.

 

Abstracts are solicited in, but not necessarily limited to, the following areas:

In this Symposium are also welcome those contributions which cover the topics beyond the above-described areas. This is done to provide the audience with a comprehensive description of Solid State Ionics. If your contribution is difficult to host within the above areas, please do not hesitate to contact directly the Conference Chairmen at ssi21@dii.unipd.it for advice.
