双级汽水分离器2设置于第一端和第二端之间，双级汽水分离器2包括相连通的低速汽水分离器22和高速汽水分离器21，高速汽水分离器21的始端与汽水出口16连通，被分离出的氢气由低速汽水分离器22的末端排出。双级汽水分离器2可以同时满足汽水的流速在高速和低速条件下的分离效率。可以理解的是，低速汽水分离器22对低速流动的汽水的分离效果较好，高速汽水分离器21对高速流动的汽水的分离效果较好，低速汽水分离器22和高速汽水分离器21中的高、低是两者相对而言的，没有绝对的高、低界限之分。
集水机构4开设于歧管主体1，集水机构4设置于双级汽水分离器2的下方， 并与双级汽水分离器2连通，以使双级汽水分离器2内的水在重力作用下流入集水机构4。排水管5设置于歧管主体1的下侧，并通过电磁阀与集水机构4连通，通过预设时间或集水机构4内的水量达到一定值时，电磁阀开启，使集水机构4内的水由排水管5排出。
加热机构6设置于集水机构4的一侧，并设置为加热电磁阀和冷却液出口18。示例性的，加热机构6包括设置于歧管主体1并依次连通的热介质流道61、热介质入口62和热介质出口63，向热介质入口62内通入热水或其他类型的热介质，热介质经过热介质流道61后，由热介质出口63排出。热介质入口62位于热介质出口63的下侧，以使热介质能够填充整个热介质流道61，并在一定时间内滞留在热介质流道61内。热介质流道61与电磁阀和冷却液出口18相邻设置，以使得热介质的热量传递给电磁阀和冷却液出口18，有效防止电磁阀和冷却液出口18冬季结冰，大大提高燃料汽车的冷启动性能。为了向加热机构6通入热介质和将热介质排出，介质管还包括与热介质入口62连通的第一热介质管77，以及与热介质出口63连通的第二热介质管78。
本实施例提供的燃料电池电堆歧管总成集成有介质接口、双级汽水分离器2、集水机构4和加热机构6，提高了燃料电池电堆歧管总成的集成度，使得燃料电池电堆歧管总成具有分离汽水中的氢气和水的作用，同时提高了燃料电池电堆歧管总成的冷启动性能。
如图3所示，高速汽水分离器21包括第一汽水腔211和多个第一挡板212，第一汽水腔211开设于歧管主体1，第一汽水腔211的上壁和下壁均连接有第一挡板212，第一挡板212与第一汽水腔211的内壁围成蛇形流道。汽水由蛇形流道流入高速汽水分离器21，汽水在流动过程中，水碰撞到第一挡板212和第一汽水腔211的内壁后，会沿第一挡板212和第一汽水腔211的内壁流到第一汽水腔211的腔底，最后由第一汽水腔211的腔底流入到集水机构4中。
低速汽水分离器22包括第二汽水腔221和多个第二挡板222，第二汽水腔221开设于歧管主体1，且为圆柱形结构，多个第二挡板222沿第二汽水腔221 的周向均匀设置，并与第二汽水腔221的径向呈夹角设置，多个第二挡板222远离第二汽水腔221的内壁的一端围成低速汽水分离器22的末端。汽水在低速汽水分离器22中旋转，并在离心力的作用下碰撞到第二汽水腔221的腔壁和第二挡板222，然后沿第二汽水腔221的腔壁和第二挡板222流至第二汽水腔221的腔底，最后第二汽水腔221的腔底流入到集水机构4中。
为实现汽水出口16和高速汽水分离器21的连通，双级汽水分离器2还包括第一连接通道23，第一连接通道23开设于歧管主体1，设置为连通汽水出口16和高速汽水分离器21的第一汽水腔211。为实现高速汽水分离器21和低速汽水分离器22的连通，双级汽水分离器2还包括第二连接通道24，第二连接通道24开设于歧管主体1，设置为连通低速汽水分离器22的第二汽水腔221和高速汽水分离器21的第一汽水腔211。
集水机构4包括集水流道41和集水腔42，集水流道41沿第一端和第二端设置的方向延伸，集水流道41的两端均连通有集水腔42，从而避免由于电堆倾斜而出现的无法排水的问题。
如图2和图3所示，两个集水腔42内均连接有电磁阀。被分离出的水可以暂存到集水腔42中，经过预设时间或集水腔42内的水量达到一定值时，电磁阀开启，使集水机构4内的水由排水管5排出。
可选地，两个集水腔42内分别设置有插针式液位传感器91，当插针式液位传感器91检测集水腔42内的水达到一定量时，电磁阀开启，使集水机构4内的水由排水管5排出。
由于集水机构4中会混合有一定的氢气，因此，可选地，电磁阀包括排水电磁阀81和排氢电磁阀82，在两个集水腔42中均设置一个排水电磁阀81，在其中一个集水腔42上设置排氢电磁阀82，排水电磁阀81和排氢电磁阀82均与排水管5连通。排水电磁阀81和排氢电磁阀82可选为功率和体积较小的蝶形电磁阀。
可选地，空气出口19、氢气入口17和冷却液入口15分别设置有第一温压 传感器92、压力传感器93和第二温度传感器94，以能够监测介质的实时状态。
如图1和图2所示，为了便于开设多个腔体和多个流道，歧管主体1包括底座11和盖设于底座11上的盖板12，底座11与盖板12盖合后形成双级汽水分离器2、集水机构4和加热机构6。空气入口14、冷却液入口15、氢气入口17、冷却液出口18、空气出口19均贯穿底座11和盖板12设置，汽水出口16贯穿底座11设置。歧管主体1采用铝合金等材料制成，材料表面做阳极氧化处理，兼具防腐蚀和轻量化的特点。
保证了底座11和盖板12之间的密封性，底座11和盖板12通过多个紧固螺栓3连接，且多个紧固螺栓3沿多个介质接口、双级汽水分离器2和加热机构6的外侧间隔设置。
为避免介质溢流，底座11和盖板12之间设置有密封圈(图中未示出)，且多个介质接口、双级汽水分离器2和加热机构6的外侧均设置有密封圈。密封圈可以采用三元乙丙橡胶(Ethylene Propylene Diene Monomer，EPDM)或树脂胶材料制成。
