Embodiment 1
[0027] see Figure 1~Figure 3 , a proton exchange membrane conductivity characterization device, combined with an electrochemical workstation or an AC impedance tester to quickly measure the conductivity of the proton exchange membrane, including a fixed frame, a membrane clamp 5 and a pressurizing device; the fixed frame is composed of an upper base plate 1. A lower base plate 2 and two support screws 3 are assembled to form an overhead installation and unloading space for the film clamp 5 between the left and right support screws 3 and between the upper base plate 1 and the lower base plate 2. Each support screw The bottom end and the top end of 3 are vertically fixedly assembled and connected with the lower base plate 2 and the upper base plate 1 respectively, the upper base plate 1 and the lower base plate 2 are arranged in parallel, and there are at least two film clamp fixing rods 4 vertically fixed and installed on the two supports on the lower base plate 2 Between the ...
Embodiment 2
[0043] This example is basically the same as Implementation 1, the special features are:
[0044] In the present embodiment, the specific test steps of the conductivity of the proton exchange membrane are as follows:
[0045] (1) Same as Embodiment 1.
[0046] (2) Same as Embodiment 1.
[0047] (3) Production of variable components:
[0048] Membrane fixture 5: Two PTFE plates of 74mm*40mm*10mm (length, width and height). There is a 10mm*10mm*1mm (length, width and depth) electrode groove in the middle of the PTFE plate, and two electrodes are drawn from both sides. 17.5mm*0.8mm*1mm wire slot. There are screw holes with a diameter of 6.5mm for fixing on the four corners of the polytetrafluoroethylene plate placed below, and there are screw holes with a diameter of 8.5mm for fixing at the four corners of the polytetrafluoroethylene plate placed above.
[0049] Electrodes: Two 10mm*10mm*1mm square platinum electrodes, both of which are led out by platinum wires with a diamet...
Embodiment 3
[0051] This example is basically the same as the previous implementation, except that:
[0052] In the present embodiment, the specific test steps of the conductivity of the proton exchange membrane are as follows:
[0053] (1) Same as the previous embodiment.
[0054] (2) Same as the previous embodiment.
[0055] (3) Production of variable components:
[0056] Membrane fixture 5: Two 74mm*40mm*10mm (length, width and height) PTFE plates, the upper and lower PTFE plates have electrode grooves of 40mm*0.8mm*1mm, two upper and lower plates, and the upper and lower plates of the membrane fixture have The distance between adjacent electrode grooves is 2 mm after the groove surfaces overlap. There are screw holes with a diameter of 6.5mm for fixing on the four corners of the polytetrafluoroethylene plate placed below, and there are screw holes with a diameter of 8.5mm for fixing at the four corners of the polytetrafluoroethylene plate placed above.
[0057] Electrodes: four cyl...
