    摘要： An air cathode having a multilayer structure is composed of at least one substrate, two diffusion layers and three activation layers. The two diffusion layers are laminated over an upper side of the substrate and a lower side of the substrate. The three activation layers are respectively laminated over one of the two diffusion layers in order. Different loadings or different kinds of catalysts are added into a slurry to form the activation layers, and the activation layers and the diffusion layers are made through simultaneous sintering, thereby shortening the processing time. When the air cathode is used as the cathode of the Zinc-Air battery, the electrolyte inside the Zinc-Air battery will not be influenced by the outside air, and the problem of maintaining the water content of the zinc anode of the Zinc-Air battery can be efficiently overcome.
