Hydrogen fuel cell stack assembling device

Abstract

The invention provides a hydrogen fuel cell stack assembling device that comprises a galvanic pile assembling platform, an air tightness tester and an angle tester; the galvanic pile assembling platform comprises a supporting plate, a support and a bearing plate; the transverse section of the support is trapezoidal, the lower bottom of the support is fixedly installed on the lower surface of the supporting plate, the bearing plate is perpendicularly connected with one end of the supporting plate, the air tightness tester is arranged around the galvanic pile assembling platform and connected with a cell stack located on the supporting plate through a pipeline, and the angle tester is arranged on the supporting plate. The device has the beneficial effects that the support is arranged belowthe galvanic pile assembling platform, so the placement mode of the galvanic pile assembling platform can be quickly adjusted by an operator according to the assembly requirements, the problem that other galvanic pile assemblies have vertical acting force on a membrane electrode in the cell stack assembly process is solved, the compression amount of the membrane electrode is effectively controlled, and the performance and the service life of the cell stack are ensured.

Description

technical field [0001] The invention relates to the technical field of battery stacks, in particular to a hydrogen fuel cell stack assembly device. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Since the fuel cell converts the Gibbs free energy in the chemical energy of the fuel into electrical energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so the efficiency is high; in addition, the fuel cell uses fuel and oxygen as raw materials; at the same time There are no mechanical transmission parts, so there is no noise pollution, and the emission of harmful gases is very small. It can be seen that from the point of view of saving energy and protecting the ecological environment, fuel cells are the most promisin...

AI Technical Summary

Problems solved by technology

[0003] As the fuel cell stack power requirements are getting higher and higher, the number of bipolar plates is also increasing. With the traditional vertical assembly, as the power of the stack increases, the membrane electrodes at the bottom of the stack, in addition to the assembly pressure It also has to bear the weight of the upper bipolar plate and end plate, and its compression will have a large change, and the excessive compression of the membrane electrode will reduce the performance and life of the stack. Therefore, some manufacturers try to assemble high-power batteries. During the stacking process, the installation angle of the battery stack will be changed to control the compression of the membrane electrode, and the traditional battery stack assembly platform can no longer meet this multi-directional assembly requirement
