The invention relates to the technical field of fuel cell vehicles, and provides a fuel cell vehicle type power cell fire suppression and purging system which comprises a whole vehicle auxiliary gas cylinder, a vehicle-mounted power cell box, a vehicle-mounted fuel cell system and a nitrogen making device, and the nitrogen making device is connected with the whole vehicle auxiliary gas cylinder through a main electromagnetic valve gas circuit. Nitrogen of the nitrogen making device is output to the nitrogen storage bottle to be stored, the nitrogen storage bottle is filled into the power battery box through the first electromagnetic valve by means of the pressure stabilizing system to restrain fire disasters, the nitrogen storage bottle is filled into the battery cathode through the second electromagnetic valve by means of the pressure stabilizing system, and the reaction flow channel and the fuel battery system purge and remove moisture. The defects that in the existing industry, a fuel cell vehicle power battery temporarily does not have a nitrogen fire suppression technology, and a fuel cell cathode, a reaction runner and a fuel cell system temporarily do not have a vehicle-mounted nitrogen purging technology are overcome.

    本发明涉及燃料电池车技术领域,提供一种燃料电池车型动力电池火灾抑制和吹扫系统,包括整车辅助气瓶以及车载动力电池箱和车载燃料电池系统,包括制氮装置,制氮装置和整车辅助气瓶之间由总电磁阀气路连接,制氮装置氮气输出至储氮瓶存储,储氮瓶利用稳压系统经过第一电磁阀充入动力电池箱抑制火灾发生,储氮瓶利用稳压系统经过第二电磁阀充入电池阴极、反应流道和燃料电池系统吹扫去除水分。解决了现有的行业内燃料电池车动力电池暂无氮气火灾抑制技术,燃料电池阴极、反应流道和燃料电池系统暂无车载氮气吹扫技术的缺陷。
