| Abstract: | The all-quinone organic redox flow battery shows promise as a low-cost, sustainable energy storage device. As most flow batteries, membranes play a critical role in the performance and cycling stability of the device. In this work, we aim to characterize the transport processes in cation exchange membranes via multicomponent diffusion theory in order to predict crossover rates, and estimate trade-offs between performance and stability. Characterization experiments on the membranes (namely: conductivity, proton transport number, electro-osmotic coefficient and permeability coefficient for quinones) allow to establish a multicomponent diffusion system of equations, solved using MATLAB. The model is validated with crossover fluxs measurements under varying conditions. The influence of thickness, water content and conductivity is assessed, for different commercial membranes (Nafion® and Fumasep). Their impact on cell performance is estimated through an in-house 1D electro-chemical model of the cells developed using COMSOL Multiphysics. This model accounts for the kinetics of the redox reactions happening at the electrode/electrolyte interface (taking in account mass and charge transports), in a flow-through graphite felt electrode with 0.2M anthraquinone (negative side) and 0.2M benzoquinone (positive side) dissolved in sulfuric acid. The model is validated using cell testing equipment provided by JenaBatteries under the scope of the FlowCamp project. |
