As electrochemical energy-conversion technologies become increasingly important in the transition to sustainable energy systems, there is a growing need to understand how the many interacting physical and chemical processes within these devices determine their performance. Practical devices must operate at high current densities to reduce system costs, placing stringent demands on the transport of reactants to the reaction sites and the removal of reaction products. Many modern electrochemical systems address these challenges by using gas diffusion electrodes (GDEs), which combine porous transport layers with ion-conducting polymers (ionomers) to enable efficient operation at high reaction rates. However, GDEs also introduce complex transport limitations across multiple length scales, including multiphase flow and coupled heat, mass, charge, and species transport.
These strongly coupled phenomena make GDE-based electrochemical systems well suited for continuum-scale multiphysics modeling.
In this webinar, we will use models created with the COMSOL Multiphysics® software to investigate the tradeoffs that govern the design and operation of GDE architectures for a range of electrochemical technologies, including CO₂ reduction, flow batteries, and hydrogen and oxygen electrochemical reactions. The models illustrate how transport phenomena across multiple length scales, together with electrochemical reaction kinetics, govern device performance and reaction selectivity. We will also examine how changes in cell architecture and operating conditions can have a greater impact on overall performance than changes in electrocatalyst materials alone, providing valuable insights into the design of electrochemical systems.
Join us to discover how multiphysics modeling can be used to understand and optimize the transport phenomena that ultimately control the performance and durability of electrochemical energy-conversion technologies.
