A novel liquid flow frame with multi-distribution channel was designed.Then, 5 kW class vanadium redox flow battery (VRB) stack composed of 40 cells each with an electrode geometric surface area of 1800 cm2 was successfully assembled.The current efficiency and energy efficiency were 93.9％ and 80.8％ at the current density 60 mA/crn2 with average output power of 5.5 kW, the higher average output power of 7.2 kW was obtained at the current density of 80 mA/cm2 with energy efficiency of 78.4％.
