In order to simplify the analysis of redox flow cells, a symmetric cell configuration is commonly employed . In this setup, the cell is connected to a single electrolyte reservoir containing one active species, maintained at a state-of-charge (SoC) of 50% . The electrolyte flows sequentially through the anodic and cathodic cell compartments before returning to the reservoir. Since the active material is simultaneously reduced at the cathode and oxidized at the anode, the SoC of the reservoir remains constant over time. Under the assumption of no side reactions, the cell operates in a steady state across a wide range of operating conditions . In these conditions, the symmetric cell can be modeled as two equivalent half-cells, meaning that a half-cell model can be constructed as a representative system of the flow cell, which is the case in the current study. This setup is effective for comparing the performance of electrode materials without the convoluting effects of membrane crossover and secondary reactions and is thus ideal for computational work.
