The invention discloses a fuel cell stack module and a vehicle. At least six fluid ports are formed in each of a cell unit of the fuel cell stack module and a body of the air inlet end plate assembly, at least two active areas are further arranged on a body of a polar plate of the cell unit, and the fluid ports are arranged on the peripheries of the at least two active areas in a surrounding manner; at least one fluid port for the circulation of the reaction medium of the battery unit is communicated with the at least two active areas, so that the number of the fluid ports is reduced. Polar plates of the battery units adopt a multi-active-region structural design, so that the active area is increased. And the fluid port can utilize the space of each side edge of the body, so that the total area of the fluid port is increased. The middle parts of the air inlet end plate assembly, the reactor core and the blind end plate assembly are all provided with fastening holes through which a fastening piece passes, so that the problem that the press-fitting force of the middle part of the active area is not uniform in the pile loading process can be solved, and a super-power single-pile scheme fuel cell is realized.
本申请公开了一种燃料电池电堆模块以及车辆。燃料电池电堆模块的电池单元以及进气端板组件的本体上均设置有至少六个流体通口,电池单元的极板的本体上还设有至少两个活性区,流体通口围设于至少两个活性区的外周,电池单元的用于供反应介质流通的至少一个流体通口与至少两个活性区均连通,减少流体通口的数量。电池单元的极板采用多活性区的结构设计,增加活性面积。并且流体通口能够利用本体的各个侧边的空间,增加流体通口的总面积。进气端板组件、堆芯和盲端端板组件的中部均设置供紧固件穿过的紧固孔,能够解决活性区域的中间部分在电堆装堆过程中的压装力不均匀的问题,实现超大功率单堆方案燃料电池。
