Description

technical field [0001] In particular, the present invention relates to an aluminum-air fuel cell system. Background technique [0002] Aluminum-air fuel cell is a new type of high-energy chemical power source. It uses aluminum alloy as the negative electrode, air electrode as the positive electrode, and neutral or alkaline aqueous solution as the electrolyte. During the operation of the battery, it consumes the aluminum alloy negative electrode and oxygen in the air. electrical energy. [0003] Aluminum-air fuel cells have the advantages of high energy density, light weight, no pollution, high reliability, and long life, but their power density is low, heat generation is large, and the temperature of the electrolyte is not easy to control. Contents of the invention [0004] The object of the present invention is to provide an aluminum-air fuel cell system with high power density and easy control of electrolyte temperature, aiming at the shortcomings of the above-mentioned...
