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 chamber and a proton exchange membrane conductivity testing method based on the testing chamber. 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. [0003] The test of the conductivity of the proton exchange membrane requires the help of a special test system, but in the related art, the test accuracy of the proton exchange membrane of the test s...
