The air electrode production equipment has simple production process and high efficiency, can realize mechanized, continuous and large-scale production, and the prepared air electrode has good consistency.
Description
technical field [0001] The invention relates to the field of metal fuel cell production, in particular to an air electrode production equipment. Background technique [0002] Metal fuel cell is a kind of semi-fuel cell, which uses metal aluminum, lithium, magnesium, zinc, etc. as fuel, and generates electricity by redox reaction with oxygen in the air. It is also called metal-air battery. Compared with batteries, it has the advantages of high specific energy, safety and environmental protection, and low price. [0003] In the redox reaction, metal aluminum, lithium, magnesium, zinc, etc. are the negative electrode of the battery, and oxygen in the air is the positive electrode of the battery. The air electrode provides the place for the oxygen reduction reaction, which is an important part of the metal fuel cell, which is mainly composed of a catalytic layer, a current collector layer, and a waterproof layer. The air electrode must be able to allow the oxygen in the air to...
