The effects of flow path structure of a redox flow battery on the discharge performance and the current density distribution were investigated. From the current density distribution measurements, it was confirmed that an interdigitated design (IDD) has a very small bias in the current density distribution upstream and downstream, and that the flow rate has a very small effect on the current density distribution in constant voltage operation, as compared with a flow-through design (FTD). The performance analysis showed that this may be due to the larger value of the surface concentration overpotential due to the slower flow velocity in the IDD.
