Title:
FUEL CELL MEMBRANE ELECTRODE SEALING ASSEMBLY, ENCAPSULATION PROCESS, AND DEVICE FOR CONTINUOUS ENCAPSULATION
Document Type and Number:
WIPO Patent Application WO/2022/116912
Kind Code:
A1
Abstract:
Disclosed is a fuel cell membrane electrode sealing assembly. The area of each diffusion layer of the fuel cell membrane electrode sealing assembly is larger than that of a through slot on each sealing frame, and position-limiting through holes are formed on a catalytic electrode layer and the sealing frames, such that preliminary position-limiting by laminating five components layer by layer is achieved. Also disclosed is an encapsulation process for the membrane electrode sealing assembly. Continuous transport of the membrane electrode sealing assembly is achieved by using a fixture, and a welding encapsulation process is combined, such that the defects in the prior art of dislocation, loosening and the like caused in the process of transporting the membrane electrode sealing assembly using the conventional hot press encapsulation technique are mitigated. Also disclosed is a device for continuous encapsulation, comprising an assembly line, a welding line, and a cooling line for the membrane electrode sealing assembly, which are all implemented in one step in a conveying process by a conveyor belt so as to achieve continuous encapsulation of a membrane electrode, thereby solving the problem that existing membrane electrode sealing assemblies cannot be encapsulated continuously.
