A battery membrane electrode testing device

Abstract

The invention belongs to the technical field of fuel cells and discloses a battery membrane electrode testing device. The battery membrane electrode testing device includes an upper fixture and a lower fixture. The upper fixture is located above the lower fixture and is arranged directly opposite to it. The upper fixture and the lower fixture are used to accommodate the battery membrane electrode to be tested; the positioning mechanism is respectively against the connected to both sides of the upper fixture and the two sides of the lower fixture; the first locking component is configured to fix the upper fixture and the lower fixture along the first direction; the second locking component is located on the lower Below the clamp, the second locking components are respectively threaded through the positioning mechanism along the second direction, wherein the first direction and the second direction are perpendicular to each other. The battery membrane electrode testing device realizes the fixation of two degrees of freedom in space. During the locking process of the first locking component and the second locking component, the upper clamp and the lower clamp will not be slightly misaligned, so that the battery to be tested The membrane electrode is more stable and flat during the clamping process.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a battery membrane electrode testing device. Background technique [0002] The membrane electrode of the fuel cell is one of the key components of the proton exchange membrane fuel cell. It needs to be accompanied by a large number of experiments and tests during the product development process. Therefore, higher requirements are put forward for the stability and reliability of the test fixture. [0003] For this reason, people develop and design fixtures and assembly methods to improve the problems caused by test fixtures as much as possible. The existing quick clamping device for battery testing adopts the pressing method of rotating the pressure plate instead of manually locking the bolts, and uses the insulating positioning rod to position the fuel cell assembly. The rotation of the upper and lower fixtures will drive the dislocation movement of the components of the uppe...

AI Technical Summary

Problems solved by technology

The existing quick clamping device for battery testing adopts the pressing method of rotating the pressure plate instead of manually locking the bolts, and uses the insulating positioning rod to position the fuel cell assembly. The rotation will drive the components of the upper half fixture and the lower half fixture to displace and move. Although the moving distance will be affected by the positioning rod, it will still cause problems with the flatness and sealing of the internal membrane electrodes.

In addition, the existing traditional fixture usually uses a heating rod to control the temperature. The heating is very uneven, and it can only be heated and cannot take away the heat. Since the pole plate of the membrane electrode test fixture needs to be used repeatedly, the membrane electrode test fixture will be thicker. Unable to achieve ideal temperature control effect
