Embodiment Construction
[0025] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] like figure 1 The shown assembly fixture for a proton exchange membrane fuel cell stack includes two splints 2 and several connecting rods 3 connecting the two splints 2; the two splints 2 are arranged on both sides of the battery stack body, and the inside of the splint 2 is hollow. Cavity 401; the connecting rod 3 is parallel and arranged along the height direction of the splint 2 (the connecting rod 3 is separately arranged on both sides of the splint 2), and the two ends of the connecting rod 3 extend into the inside of the two splints 2 respectively, and are connected with the locking device 4 are connected, and the locking device 4 is set in the cavity 401.
[0027] like figure 2 As shown, the locking device 4 includes a movable rod 402, a rack 403, several gears 404 and a lim...

The invention discloses a proton exchange membrane fuel cell stack assembly fixture, comprising two clamping plates, a plurality of connecting rods connecting the two clamping plates, and a locking device; Cavities; the connecting rods are arranged in parallel and along the height direction of the clamping plates, two ends of the connecting rods respectively extend into the interior of the two clamping plates, and are connected with the locking device, and the locking device is arranged in the cavity. The beneficial effects of the present invention are as follows: the present invention uses the movable rod on the splint, when the movable rod moves from one end to the other end, the movable rod will drive the rack to move, use the rack and pinion structure to drive the limit block to rotate, and use the limit block to clamp The connecting rod can be locked by entering the limit slot, and the operation process is simple; and when the movable rod moves, multiple connecting rods can be fixed at one time, which improves the efficiency of the installation and removal of the stack body by the staff, saves time, and reduces the cost of Cost of production.
Description
technical field [0001] The invention relates to a fixture, in particular to a proton exchange membrane fuel cell stack assembly fixture. Background technique [0002] In principle, the proton exchange membrane fuel cell is equivalent to the "reverse" device of water electrolysis. The single cell is composed of an anode, a cathode, a proton exchange membrane, and a catalytic layer. The anode is the place where the hydrogen fuel is oxidized, and the cathode is the place where the oxidant is reduced. [0003] Proton exchange membrane fuel cell is a kind of fuel cell, and its stack usually needs to be fixed with corresponding clamps. The existing fixtures are connected by simple splints and threaded columns, and the nuts need to be screwed one by one during installation and connection. The connection efficiency is low, resulting in high time and cost for production. Contents of the invention [0004] The purpose of the present invention is to provide a proton exchange membran...
