Abstract

The invention provides a hydrogen fuel cell membrane electrode assembly suitable for batch production and a production process thereof. The hydrogen fuel cell film electrode assembly comprises a gas diffusion layer, a catalyst layer and a perfluorosulfonic acid resin film, and also comprises a protective film frame, wherein each side of the perfluorosulfonic acid resin film is sequentially and uniformly coated with one catalytic layer, and one protective film frame and one gas diffusion layer are adhered to each side of the perfluorosulfonic acid resin film; an inner edge of the protective film frame is closer to the center of the perfluorosulfonic acid resin film by 1-2mm than the outer edge of the gas diffusion layer; the protective film frame is adhered to the perfluorosulfonic acid resin film through an adhesive; the gas diffusion layer is adhered to the protective film frame through an adhesive, the coating width of the adhesive is less than 1mm, and the distance between the adhesive and the outer edge of the gas diffusion layer is 1-2mm. By adopting the hydrogen fuel cell film electrode assembly, the mechanical strength and the service life of the film electrode assembly are ensured, and meanwhile, the film electrode assembly can be automatically produced in batches.

Description

technical field [0001] The invention relates to the field of proton exchange membrane fuel cells, in particular to a hydrogen fuel cell membrane electrode assembly suitable for mass production and a production process thereof. Background technique [0002] As an energy conversion device, a hydrogen fuel cell can convert the chemical reaction process between hydrogen and oxygen into electrical energy output, and can generate a large amount of heat energy and water. Its environmental friendliness is increasingly recognized and supported by the general public . [0003] Membrane electrode assembly (MEA) is the power generation unit of the fuel cell. Improper sealing structure will not only affect the appearance and sealing of MEA, but also lead to the reduction of performance and life. The patent with the publication number CN201060896Y discloses a composite membrane electrode for a proton exchange membrane fuel cell. The membrane electrode sealing structure introduced in this...
