本文以模擬釩液電池的三維模型，並以蛇型流道做為基礎，模擬出有加擋板和未加擋板的離子濃度變化及電壓變化，將擋板放置於流道中有益於提升電池效率，論文中也探討了擋板高度及個數的影響，在高度0.9h有較顯著的效應，而個數設為九較其他個數也有較顯著的效果，擋板在流道中的排列方式也有4種Case的比較，其中以Case 4的排列方式比起其它Case電壓及離子濃度有較好的反應。
本文實驗透過控制不同參數(電流密度、電解液流速)探討電池的電壓效率、庫倫效率及能量效率，並利用三種流道分別是空流道、蛇型流道及有加擋板的蛇型流道，實驗中發現在較低的電流密度(40mA/cm2)及調高電解液流速(300ml/min)會有較好的能量效率，而在相較於空流道，蛇型流道的能量效率較空流道提升了3.24 %，Case 4 的能量效率相較於蛇型流道提升了3.5 %。

This thesis establishes a vanadium redox flow battery 3-D numerical model. Simulate the ion concentration change and the terminal voltage with adding the baffles based on the serpentine flow path. The results show that the adding the baffles will affect the battery efficiency.
The author also did research on the effect of the height of the baffles and the number. Setting the height of the baffles of 0.9h and number with 9 has a better effect for the battery. There are four kind of cases by installing 9 baffles and 4 arranging types in the entire serpentine flow. Case 4 has a better voltage and ion concentration reaction than the other cases.
The unit tests cell performances are analyzed on the voltage efficiency, coulombic efficiency and energy efficiency under different parameters. There are three kinds of channels, without flow field, with serpentine channel, and serpentine channel adding baffles. It can be found from the experiment that the better energy efficiency will occur at the lower current density (40 mA/cm2) and higher flow rate (300 ml/min). Compared with the channel without flow field, the smooth channel has a higher energy efficiency about 3.24 %. In addition, Case 4 has a higher energy efficiency about 3.5 % than the smooth channel.
