Various researchers have studied methods for improving the microstructural features of the electrode influencing the flow cell performance, while others have focused on creating and developing electrode materials with desired chemical and physical properties. These contributions include studying the role of electrode materials , electrode orientation , different weave patterns of the fibers , coating of the electrode , and taking advantage of nano-fibers and electrografting , just to name a few. In addition to these efforts, engineering the electrodes has gained attention recently as an efficient approach to increase the performance of electrochemical flow reactors . In order to engineer the porous electrodes, one should tackle the challenge of making a balance between generating high surface area for maximizing reaction kinetics and simultaneously minimizing the pressure drop over the entire electrode. In combination with experimental research, computational techniques have the potential to accelerate and guide the design of porous electrodes.
