Description

Technical Field

[0001] The invention belongs to the technical field of green hydrogen production, and in particular relates to a device for flipping polar plates. Background Art

[0002] As a clean and renewable energy, hydrogen energy is one of the ideal energy sources for sustainable development. The development of hydrogen energy is a key direction of strategic emerging industries. Hydrogen energy has a wide range of application scenarios. It can achieve large-scale peak regulation of power grids and cross-seasonal and cross-regional energy storage, and accelerate the low-carbonization of industries such as industry, construction, and transportation.

[0003] The alkaline water electrolysis hydrogen production device consists of an electrolyzer and an auxiliary system. The core components of the alkaline electrolyzer mainly include plates, sprayed nickel mesh, diaphragm cloth, gaskets and fasteners. Among them, the plate is one of the most critical core components of the alkaline electrolyzer. As a supporting component of the electrolyzer structure, the plate is mainly used to support the hydrogen and oxygen side electrodes and electrolytic diaphragm cloth in a single electrolytic chamber, and provide hydrogen, oxygen, and alkali liquid channels to separate the hydrogen produced by the cathode and the oxygen produced by the anode in a single chamber, ensuring the safety of the electrolyzer operation. Before the electrolyzer is assembled, the front and back press sheets of the hydrogen, oxygen, and alkali liquid channels of the plate need to be pasted. The traditional plate flipping and front and back press sheeting are all done manually. This method is time-consuming and labor-intensive, increases the production cost of the electrolyzer equipment, and in a certain sense limits the development of hydrogen energy.

[0004] With the rapid development of the hydrogen energy industry, the gas production and volume of single electrolyzers are getting larger and larger, and the number of small chambers in a single electrolyzer is also increasing accordingly. The traditional manual method of flipping and pressing and pasting the front and back sides is no longer applicable. Summary of the invention
