Abstract: 본발명은레독스흐름전지의매니폴드구조에관한것으로서, 보다구체적으로전해액균등분배유로구조를갖는매니폴드및 이를채용하는레독스흐름전지에관한것이다. 본발명에따른매니폴드는레독스흐름전지에적용시 전극전해액이좌우대칭되는유로를통해균등하게분배되어주입됨으로써전극과전해액의반응성이향상되고단위셀 스택의성능을높일수 있게된다. 또한전해액균등분배유로를따라전해액의이동거리가길어지게됨에따라전도성을가지는수계전해액의저항이증가하게됨으로써반응부의션트전류(shunt current) 발생을억제하여전지의성능을향상시킬수 있다.
Abstract translation: 本发明涉及一种氧化还原液流电池的歧管结构，更具体地说，涉及一种具有电解液均匀分布流路结构的歧管和采用该歧管的氧化还原液流电池。 根据本发明的歧管可以在施加到氧化还原液流电池上时通过双向对称流动路径均匀地分布和注入电极电解质，从而增强电极和电解质的反应性，并提高单电池堆的性能。 此外，由于导电性含水电解质的电阻随着电解质的均匀分布流路的电解质的移动距离变长而增加，因此可以防止反应单元中的分流电流的发生，并且可以提高电池的性能。
