Symposium EN09—Flow-Based Open Electrochemical Systems
An open electrochemical system involves one or more reagents circulating through cell compartments for electrochemical reactions. The flow-based systems span over a variety of systems such as flow batteries, fuel cells, electrolyzers, capacitive deionization, flow synthesis, etc. for applications in grid and transportation energy storage, water desalination, catalysis, hydrogen production, and large-scale chemical production. Although significant progress has been achieved, materials development has represented common challenges for these technical fields, which have hampered the widespread commercial update of these technologies. Especially, the fundamental understandings of electrochemical processes and mechanisms in these systems are rather limited, including experimental and computational approaches for elucidating solvation structures, electrolyte/electrode interfaces, new membranes and electrodes, failure/degradation pathways, and transport properties. The knowledge is critically important to achieve technical breakthroughs and enable ubiquitous technological implementation. Moreover, high-level developmental needs have been identified for system-level optimizations, such as stack prototype, flow field, safety diagnostics, cost analysis, and field analytics. In addition, recent hybrid flow technologies integrating two or more electrochemical systems, such as solar flow batteries, photocatalytic fuel cells, continuous-flow synthesis of battery materials, have opened a promising avenue to harvest the advantages of both technologies. This symposium will encourage discussion of new concepts and challenges at the cutting-edge through both fundamental and applied studies of materials and systems. It will bring together a diverse mix of leading researchers and emerging talents to promote further synergy across fields.
