Renewable energy is important source for recent civilization. However renewable energy sources such as solar cell, wind power requires flexible energy storage system. Vanadium Redox Battery(VRB) is the rechargeable chemical cell. Storage tank and reaction cell of VRB are separated so that it is easy to control power and energy capacity independently. VRB cell use porous carbon electrodes to increase active surface area. Also VRB use flow channel structure to enhance mass transportation of electrolyte of cell. Already knows that flow channel figure such as parralell, interdigitated, serpentine could change battery performance. In this study,locates channel at inside of porous electrode to combine flow through and interdigitated cell desing. Compare no channel, Ordinary channel and modified channel design. Inside channel structure showed advanced cell efficiency. It reduce pressure drop of cell as ordinary design. Modified structure helps electrolyte flow entire electrode area. Efficent electrolyte flow improved electrical characteristics Reserch use COMSOL to simualate VRB process. |
