Integrated structure of ion filter and reservoir

According to an embodiment of the present invention, an integrated structure of an ion filter and a reservoir is provided. The integrated structure of the ion filter and the liquid storage device comprises the liquid storage device for storing cooling liquid for cooling the fuel cell stack; the ion filter is positioned in the liquid storage device; the control valve is positioned in the liquid storage device and is opened or closed, so that the cooling liquid flows into the ion filter; wherein the reservoir is divided into a first region in which the ion filter is located by opening or closing the control valve and a second region which is a space other than the first region, and the first region and the second region are connected by an air ventilation unit through which air passes. 根据本发明的实施方式，提供了一种离子过滤器和储液器的集成结构体。离子过滤器和储液器的集成结构体包括：储液器，储存用于冷却燃料电池组的冷却液；离子过滤器，位于储液器内部；以及控制阀，位于储液器内部，以打开或关闭，使得冷却液流入离子过滤器中；其中，储液器被分成第一区域和第二区域，通过打开或关闭控制阀，离子过滤器位于所述第一区域中，第二区域是除第一区域之外的空间，并且第一区域和第二区域由空气通过的空气通气单元连接。
