Abstract

The invention is applicable to the technical field of flow batteries, and provides a leak detection device for an ion exchange membrane of a flow battery, comprising: two end plates which are oppositely arranged and between which an ion exchange membrane is placed; the sealing strip is used for sealing between the ion exchange membrane and the end plate, is mounted on the side wall, close to the ion exchange membrane, of the end plate, and is connected end to end to form a closed loop; gas access holes are respectively formed in two ends of the two end plates, and orifices in one ends of the gas access holes extend to the inner side of the sealing strip and are communicated with the space close to one side of the ion exchange membrane; the invention further discloses a testing method, the end plates, the sealing strips, the gas conveying pipes, the pressure gauges and the gas valves are arranged, the structure is simple, manufacturing and assembling are easy, the production cost is low, operation is convenient, and the testing efficiency is high. The leak detection process of the flow battery ion exchange membrane is simplified, and the leak detection accuracy of the ion exchange membrane is improved.

Description

technical field [0001] The invention belongs to the technical field of liquid flow batteries, and in particular relates to a leak detection device and a testing method for an ion exchange membrane of a liquid flow battery. Background technique [0002] Flow battery is an electrochemical energy storage technology and a new battery. The liquid flow battery is composed of a point stack unit, electrolyte, electrolyte storage and supply unit, and management control unit. ) wide, long cycle life characteristics. [0003] At present, in the material testing of flow batteries, the detection of ion-exchange membranes mainly depends on the supplier's self-inspection certification, while the user's inspection of ion-exchange membranes is mainly through observation and trial operation of assembled stacks. The observation method is not accurate enough for leak detection, and it is cumbersome and time-consuming to assemble a stack for trial operation. Contents of the invention [000...
