A hydrogen fuel cell stack assembly device

Abstract

The invention provides a hydrogen fuel cell stack assembly device, which includes a stack assembly platform, an air tightness tester and an angle tester. The stack assembly platform includes a support plate, a bracket and a pressure plate. The bottom is fixedly installed on the lower surface of the support plate, the pressure bearing plate is vertically connected to one end of the support plate, the air tightness tester is set around the battery stack assembly platform, and is connected to the battery stack on the support plate through pipelines, and the angle tester set on the support plate. Beneficial effects of the present invention: In the present invention, by setting a bracket under the stack assembly platform, the operator can quickly adjust the placement of the stack assembly platform according to the assembly needs, so as to solve the problem of the presence of other stack components on the membrane electrodes during the battery stack assembly process. The problem of vertical force is effectively controlled by the compression of the membrane electrode, so as to ensure the performance and service life of the battery stack.

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...

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
