Abstract

The invention discloses a proton exchange membrane conductivity test system, which includes a test chamber, a humidity adjustment device, a temperature adjustment device, a pressure adjustment device, an electrochemical workstation and a control terminal. The test chamber includes a chamber body and a test fixture, and the test fixture is located at In the chamber; the humidity regulating device includes a humidity sensor, a hydrogen storage tank, a nitrogen storage tank, a first controller, a second controller and a humidifier, and the inlets of the first controller are all communicated with the hydrogen storage tank and the nitrogen storage tank. Both the inlets of the two controllers are connected with the hydrogen storage tank and the nitrogen storage tank, the outlets of the first controller and the second controller are connected with the inner cavity of the warehouse body, and the humidifier is connected in series between the second controller and the warehouse body Between; the humidity adjustment device, the temperature adjustment device, and the electrochemical workstation are all electrically connected to the control terminal. The proton exchange membrane conductivity test system of the invention enables test samples to be placed in a stable environment of humidity and temperature, thereby ensuring the accuracy of the test sample conductivity.

Description

technical field [0001] The invention relates to the technical field of proton exchange membrane conductivity testing, in particular to a proton exchange membrane conductivity testing system. Background technique [0002] A hydrogen fuel cell is a power generation device that converts the chemical energy of hydrogen and oxygen directly into electrical energy. Proton exchange membrane is an important part of hydrogen fuel cells, which plays a key role in the performance of hydrogen fuel cells. Conductivity is an important physical parameter of the proton exchange membrane as it reflects the ability of the proton exchange membrane to form a current through a certain concentration of protons. In the related art, the conductivity testing device and testing method of the proton exchange membrane have the problems of unstable and inaccurate testing temperature, humidity, pressure, etc., and the testing result of the conductivity cannot be guaranteed.
