Problems solved by technology

However, when the fuel cell automatic stacking device is fixed with screws, it is not only necessary to use professional tools (such as wrenches, etc.) to manually fix the compressed fuel cell stack together, resulting in low fuel cell stack assembly efficiency , cost increase; and in order to ensure the structural stability of the fuel cell stack, it is often necessary to use multiple pairs of screws to achieve the purpose of fastening, but this will aggravate the problem of uneven force due to the difficulty in the uniform fastening force of multiple screws , especially once the fastening force of the same pair of screws is different, it is very easy to cause the fuel cell monomer to warp or deform, and the sealing performance of the fuel cell stack cannot be ensured

Embodiment 1

[0073] In order to realize the automatic assembly of the fuel cell stack, improve the assembly efficiency, reduce the assembly cost, and achieve uniform stress on each part of the fuel cell stack, an embodiment of the present invention provides an assembly equipment for the fuel cell stack. Such as figure 1 As shown, the equipment mainly includes a conveying device 1 , a pressing device 2 , a binding device 3 and a fixing device 4 . The conveying device 1 is used to transport the stacked fuel cells to the bundling station 10, and the pressing device 2 is used to carry out the packing of the fuel cells on the bundling station 10. Pressing and compressing, the binding device 3 and the fixing device 4 work together to bind the compressed fuel cell cells to assemble a fuel cell stack 5 .

[0074] It is worth noting that, since the assembly equipment of the present application can directly transport the stacked fuel cells to the bundling station 10 through the conveying device 1, ...

Embodiment 2

[0110] On the basis of the above-mentioned embodiment 1, the embodiment of the present invention further provides a fuel cell stack assembly method, which can also be said to be a method of using the fuel cell stack assembly equipment described in the first embodiment. Such as Figure 11 As shown, the method of use mainly includes:

[0111] S10, using a conveying device to convey the stacked fuel battery cells to a bundling station.

[0112] When stacking, multiple fuel cell cells can be manually stacked directly, or a plurality of fuel cell cells can be automatically grabbed by a mechanical arm for stacking, which is not specifically limited here. After the stacking is completed, the stacked fuel cells are automatically transported to the bundling station 10 by the transport device 1 .

[0113] S20, using a pressing device to press the plurality of fuel battery cells on the bundling station, so as to compress the plurality of fuel battery cells.

[0114] Driven by the powe...

Abstract

The invention discloses assembly equipment of a fuel cell stack and a use method of the assembly equipment. The assembly equipment comprises: a bundling device which is used for storing a plurality of bundling elements in a releasable manner and synchronously tensioning after the plurality of bundling elements jointly wind a plurality of compressed fuel cell monomers; and a fixed connection device which is used for fixedly connecting the plurality of strained strapping elements to form an annular strapping space, so that the plurality of compressed single fuel cells are bound in the strapping space. The bundling device comprises a plurality of reels and a driving device in driving connection with the reels, each reel can contain one bundling element in a releasable mode, each reel rotates forwards under the action of external force so as to release a corresponding bundling element, and each reel rotates reversely under the driving action of the driving device so as to tension the corresponding bundling element. According to the scheme, a plurality of fuel cell monomers can be firmly and quickly wound, so that each part of the fuel cell stack is uniformly stressed, the assembly efficiency is greatly improved, and the assembly cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and more specifically relates to a fuel cell stack assembly device and a method for using the same. Background technique [0002] A fuel cell is a power generation device that converts chemical energy in fuel directly into electrical energy through electrochemical reactions. However, the voltage and output power that a single fuel cell (or fuel cell unit) can provide is relatively low. In practical applications, generally multiple fuel cell cells are stacked together to form a fuel cell stack capable of high voltage and high power output. Correspondingly, the fuel cell stack of the fuel cell is formed by stacking multiple fuel cell cells. [0003] The fuel cell stack of the fuel cell needs to maintain a stable structure during use to ensure that the fuel cell maintains a stable and continuous power output. The fuel cell stacks of existing fuel cells mostly use fastening means, such as screw...
