A method is provided for producing electrodes of flow cell having high power density. A plurality of seeds are distributed on a surface of a conductive carbon material. The seeds are etched into nanoparticles to form carbon nanotube (CNT) electrodes. The present invention can be applied to vanadium redox flow cell with advantages of the CNT electrodes, such as conductivity, corrosion resistance, mechanical strength and specific and electrochemical surface area. Electrons are directly passed to the material through CNTs and then to an external electronic load for improving power density of flow cell, making a cell pack more compact and reducing energy consumption on charging and discharging without using noble metal material.

Method of fabricating electrodes of high power-density flow cell

A device is provided for detecting a charging and discharging status of a flow-cell pack. During charging and discharging course of the flow-cell pack coordinated with electrolyte storage tanks and actuators, ultrasonic sensors of ultrasonic detection devices are used to sense sonic vibration generated by fluid flow in the flow-cell pack. Thus, the charging and discharging status of the flow-cell pack is detected for adjusting related parameters. The present invention has a simple structure, runs without using extra power supply, does not hinder performance of flow cell, and obtains charging and discharging status of flow cell accurately and rapidly.
