Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, specifically to a hydrogen fuel cell electrode coating processing equipment. Background Technology

[0002] A hydrogen fuel cell is a device that uses hydrogen as fuel and directly converts chemical energy into electrical energy through an electrochemical reaction. Based on the redox reaction of hydrogen and oxygen at the electrodes, hydrogen is oxidized at the anode, releasing electrons and protons. Electrons flow through an external circuit to generate an electric current, while protons are transferred through the electrolyte to the cathode. At the cathode, oxygen is reduced and combines with protons and electrons to form water. In this process, chemical energy is efficiently converted into electrical energy. The electrode coating equipment is crucial in the production of metal bipolar plates for fuel cells; its technical level and performance directly affect the corrosion resistance, conductivity, and service life of the bipolar plates.

[0003] Chinese Patent Publication No. CN221951509U, authorized on November 5, 2024, discloses a fuel cell bipolar plate coating device, including a frame. A screw is installed on the inner wall of the frame, and a movable groove is sleeved on the outer wall of the screw. A sleeve groove is installed at the bottom end of the movable groove. In use, a motor drives the screw to rotate, thereby completing the threaded transmission of the movable groove on the outer wall of the screw through the internally and externally adapted threads. This allows for the adjustment of the overall vertical and horizontal position of the connecting pipe, enabling reciprocating left and right adjustment of the spraying position. Repeated left and right spraying ensures more uniform spraying. The spray height of the nozzle can be raised and lowered by holding the connecting pipe. A corrugated pipe is connected to the top of the connecting pipe, providing a certain range of extension and retraction, allowing the connecting pipe to extend and retract within the sleeve groove. This allows for adjustment of the fixed spraying height without affecting the supply of spraying liquid, enabling adjustment of both spray height and range, resulting in greater overall adaptability.

[0004] Existing coating equipment uses spraying to form a uniform coating on the electrode surface. However, this coating method will block part of the electrode surface, requiring multiple spraying processes, which is time-consuming and labor-intensive. It can also easily lead to uneven coating on the electrode surface, reducing the coating effect and failing to meet the usage requirements. Utility Model Content
