The invention discloses a spraying device capable of customizing a spraying area and a membrane electrode spraying system. The spraying device capable of customizing the spraying area comprises a base, a spraying structure and air injection structures. The spraying structure is arranged on the base. The air injection structures are arranged on the base, and the air injection range of the air injection structures is partially overlapped with the spraying range of the spraying structure so as to limit the spraying range of the spraying structure. The air injection structures are arranged on the base, when the spraying structure conducts spraying, the air injection range of the air injection structures is partially overlapped with the spraying range of the spraying structure, the air injection structures inject air to form an air wall, the air wall can stop raw materials sprayed out by the spraying structure, and the sprayed raw materials are limited to one side of the air wall. The effect of limiting the spraying range of the spraying structure is achieved, the raw materials sprayed out of an effective attachment area during spraying are reduced, and the utilization rate and the spraying efficiency of the catalyst raw materials are improved.
Description
technical field [0001] The invention relates to the field of spraying equipment, in particular to a spraying equipment for customizing a spraying area and a membrane electrode spraying system. Background technique [0002] With the development of technology, fuel cell, as one of the key development directions of new energy, has the advantages of high efficiency and no pollution. Among them, the membrane electrode is the core component of the fuel cell. The membrane electrode includes a proton exchange membrane and a catalyst. The catalyst is generally attached to the proton exchange membrane by spraying. [0003] In the existing membrane electrode spraying equipment, the catalyst slurry is generally atomized and sprayed towards the proton exchange membrane through a nozzle, so that the catalyst is attached to the proton exchange membrane. However, in the existing structure where the catalyst slurry is atomized and sprayed through the nozzle, some atomized catalyst may be sp...
