چکیده انگلیسی
We present a vanadium redox flow battery with a tubular cell design which shall lead to a reduction of cell manufacturing costs and the realization of cell stacks with reduced shunt current losses. Charge/discharge cycling and polarization curve measurements are performed to characterize the single test cell performance. A maximum current density of 70Â mAcmâ2 and power density of 142Â Wlâ1 (per cell volume) is achieved and Ohmic overpotential is identified as the dominant portion of the total cell overpotential. Cycling displays Coulomb efficiencies of â95% and energy efficiencies of â55%. During 113Â h of operation a stable Ohmic cell resistance is observed.
