Cell membrane electrode testing device

Abstract

The invention belongs to the technical field of fuel cells, and discloses a cell membrane electrode testing device. The cell membrane electrode testing device comprises an upper clamp, a lower clamp,positioning mechanisms, a first locking assembly and a second locking assembly, wherein the upper clamp is located above the lower clamp and is opposite to the lower clamp, and a to-be-tested cell membrane electrode is accommodated between the upper clamp and the lower clamp; the positioning mechanisms abut against the two sides of the upper clamp and the two sides of the lower clamp respectively;the first locking assembly is configured to fix the upper clamp and the lower clamp in a first direction; and the second locking assembly is located below the lower clamp, the second locking assemblyis arranged on the positioning mechanisms in a penetrating mode in a second direction, and the first direction and the second direction are perpendicular to each other. According to the cell membraneelectrode testing device, the fixation in two spatial degree-of-freedom directions is realized, and the upper clamp and the lower clamp are not slightly misplaced in the locking process of the firstlocking assembly and the second locking assembly, so that the to-be-tested cell membrane electrode is enabled to be more stable and smooth in 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
