Problems solved by technology

[0013] This reaction will produce hydrogen gas and consume aluminum, but does not generate electricity. The energy is generated in the form of heat, which will reduce the energy output efficiency of the battery, and the temperature of the electrolyte will increase with the accumulation of heat inside the battery. Increased evaporation

Description

technical field [0001] The invention relates to an aluminum-air fuel cell system, in particular to an aluminum-air fuel cell system with a temperature control system, a hydrogen exhaust system, a filter system, and a recirculating electrolyte. Background technique [0002] A metal-air fuel cell is a chemical power source that uses oxygen in the air as the positive electrode, a metal as the negative electrode, and a neutral or alkaline electrolyte as the medium. Under the action of a catalyst, a chemical reaction occurs to generate electrical energy. Among them, the metal is used as the anode, which is oxidized and dissolved during the discharge process to release electrons, and the oxygen in the air is used as the cathode active material. During the discharge process, the electrons diffused through the air electrode into the battery and received from the external circuit are reduced. Compared with other batteries, the unique feature of the metal-air battery is that the posit...
