Description
Summary:A multiphysics model of a flow battery fibrous cathode was designed in COMSOL. A seven level parametric study was performed to determine the effect of a variety of physical and chemical parameters on overall cell performance. It was found that kinetic factors dominate the operation and performance however certain morphological properties, such as fiber diameter, porosity and anisotropy, could be modified to optimize cell performance. It was also found that further optimization could be performed on engineering parameters such as the electrode thickness and design of the flow distributor. Due to the strong dependence on porosity, future studies will take into account membrane compression.
