• H121 Reaction and Transport Simulation around Fiber Electrodes in a Redox Flow Battery

抄録

Numerical investigation on two-dimensional flow fields and reaction distributions in a Vanadium redox flow battery with single and double fiber electrode geometry has been performed. Simulation results in a single fiber geometry showed cell performance deteriorated by less electrolyte flow velocity and formation of concentration boundary layer around the fiber electrode in high current density operation. In a double (tandem) fiber geometry, local depletion of reactive species around a 2nd fiber electrode was observed, resulting in inhomogeneous current distribution on the surface of electrodes that caused excess overpotential.
