FAQS 4
What is a vanadium redox flow battery?
A vanadium redox flow battery consists of several basic elements: a flow cell (stack), which are fuel cells wherein an electrochemical reaction occurs; a hydrodynamic system, including pumps, flow sensors and a pressure pump control system; and electrolyte tanks [ 6 ]. Flow batteries require several stacks to achieve the desired performance [ 7 ].
Which flow cell design is best for a stack-scale battery?
Serpentine and interdigitated flow fields are the most frequently studied and compared designs. It is found that the overall battery performance heavily depends on the balance between the electrochemical polarizations and pumping work . More significantly, there exist many issues when scaling up the flow cell toward the stack-scale batteries.
