description The invention discloses a proton exchange membrane air tightness detection device, which comprises an air tank and a water tank which can be communicated with the air tank through a pipeline, and the free end of the pipeline can extend into the water of the water tank so as to judge the air tightness of a proton exchange membrane by observing whether bubbles are generated in the water tank; wherein a pressure reducing valve, a pressure gauge and a sealing tool are arranged in the pipeline along the flowing direction of the gas, and in a detection state, the pressing machine can seal a to-be-detected area of the proton exchange membrane in the sealing tool for gas tightness detection. The device is simple to operate, and overcomes the defects of high price and complex operation of the existing professional detection equipment while realizing the air tightness test of the proton exchange membrane. 本发明公开了一种质子交换膜气密性检测装置，包括空气罐和能通过管路和所述空气罐连通的水槽，且所述管路的自由端能伸入所述水槽的水中以通过观察其中是否产生气泡判断质子交换膜的气密性；其中，沿气体的流动方向在所述管路中设置有减压阀、压力表
