[0002] The membrane electrode sprayer is a high-tech equipment specially used for preparing membrane electrodes for fuel cells. The membrane electrode is one of the core components of fuel cells. It contains catalysts, proton exchange membranes and gas diffusion layers. Spraying technology is an effective method for preparing membrane electrodes. It can achieve nano-level thickness spraying and improve catalytic activity. It can also achieve large-scale, continuous production and improve production efficiency.

[0003] During the existing membrane electrode spraying, the membrane electrode is first placed on a square-shaped fixture, the membrane electrode is fixed, and finally the membrane electrode surface is sprayed. However, each of the existing fixtures can only be used for one specification of membrane electrode, and the applicability of the fixture is narrow, which indirectly increases the production cost. During the membrane electrode spraying process, it needs to be turned over, and the operator needs to use a vacuum suction plate to manually peel off the film and turn it over. This process can easily cause the surface of the membrane electrode to curl and the spraying area to be misaligned, affecting the spraying quality. Utility Model Content
