Description

Stacking System of Fuel Cells The present invention relates to a stacking system for fuel cell cells, and more specifically, to a stacking system for fuel cell cells that reduces cycle time. Generally, the electrolysis of water produces hydrogen and oxygen, and a hydrogen fuel cell is a device that utilizes the reverse reaction of this electrolysis. The above hydrogen fuel cell refers to a device that produces electricity and heat by supplying hydrogen extracted from sources such as petroleum or gas as fuel and reacting it with oxygen in the air. Unlike conventional chemical batteries, these hydrogen fuel cells can continuously generate electricity as long as fuel and air are supplied, and they are more energy-efficient and noise-free compared to turbine power generation methods that use fossil fuels. Furthermore, the aforementioned hydrogen fuel cell is an eco-friendly energy source with low greenhouse gas emissions and is a new energy source applicable in various fields such as transportation, power generation, household use, and portable applications. The hydrogen fuel cell described above is a combination of multiple hydrogen fuel cell cells. The above hydrogen fuel cell cell is manufactured by stacking a negative electrode, a negative electrode gasket, a gas diffusion layer, a membrane electrode assembly, and a positive electrode. However, when manufacturing a hydrogen fuel cell according to conventional technology, there is a problem in that the manufacturing of the hydrogen fuel cell is not fully automated, such as when the negative electrode, negative electrode gasket, gas diffusion layer, membrane electrode assembly, and positive electrode are stacked one by one by a worker's manual labor, or when automation is limited to localized parts such as the movement of each component. In addition, the hydrogen fuel cell according to the prior art has the disadvantage of reduced productivity due to increased cycle time, as the hydrogen fuel cell is formed by stacking approximately 1,000 or more of the above-mentioned negative electrode, negative electrode gasket, gas diffusion layer, membrane electrode assembly, and positive electrode. The matters described in this background technology section are written to enhance understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art to which this technology belongs.
