Problems solved by technology

[0005] In practical applications, it is usually necessary to assemble multiple single cells in series to form a fuel cell stack for use. At present, fuel cell stacks are mostly stacked manually. Manual stacking has low stacking efficiency and high labor intensity. , quality is difficult to guarantee and high inconsistency and other issues

Embodiment Construction

[0026] Such as figure 1 As shown, a device for assembling a fuel cell stack includes a bracket 1 on which a first lifting plate 21, a second lifting plate 31, and a third lifting plate 42 are arranged. The first lifting plate 21 is used to place For the bipolar plate 2 , the second lifting plate 31 is used to place the MEA 3 , and the third lifting plate 42 is used to place the storage plate 4 . The storage plate 4 is located in the middle, and the bipolar plate 2 and the MEA3 are respectively placed on both sides of the storage plate 4 . The 4 corners of receiving plate 4 are provided with retaining rod 41 respectively.

[0027] The support 1 is provided with a first vertical lead screw 23 driven by a second motor 22, the first lifting plate 21 is lifted by a first drive plate 24 that cooperates with the first vertical lead screw 23, and the second motor 22 drives the first A vertical lead screw 23 rotates to make the first drive plate 24 move up and down along the first ve...

Abstract

The invention discloses a device for assembling a fuel cell stack, comprising: a bracket; a first lifting plate, arranged on the bracket, for placing a bipolar plate; a second lifting plate, arranged on the bracket , for placing the MEA; the third lifting plate, set on the bracket, for placing the storage plate; the first transfer mechanism, for transferring the bipolar plates one by one to the storage plate for stacking; the second transfer mechanism , for transferring the MEAs one by one to the storage plate for stacking; the pressing plate is liftably arranged above the storage plate, and is used for squeezing the stacked bipolar plates and MEAs. The device of the present invention transfers the bipolar plates one by one to the storage plate for stacking through the first transfer mechanism, and transfers the MEA one by one to the storage plate for stacking through the second transfer mechanism, and the bipolar plates and MEAs are stacked alternately. Then use the pressure plate to press down to make the assembly between the bipolar plate and the MEA compact, and complete the automatic device of the fuel cell stack.

Description

technical field [0001] The invention relates to the technical field of fuel cell assembly, in particular to a device for assembling a fuel cell stack. Background technique [0002] A fuel cell is a chemical reaction device that directly converts chemical energy in fuel into electrical energy. Due to the high specific energy of the fuel and the simple structure of the fuel cell system, the fuel cell has broad application prospects in the fields of vehicle power supply and portable mobile power supply. [0003] The invention with the publication number CN110416571A discloses a fuel cell stack structure, including a cathode end plate, a bipolar plate, an MEA assembly, and an anode end plate, wherein a first sealing member is fixed on the side of the MEA assembly frame facing the anode side, A second sealing part is fixed on the side of the frame of the MEA component facing the cathode side, the first sealing part fits with the anode-side sealing groove for press-fit sealing, a...
