Problems solved by technology

However, in the chemical reaction of the existing metal-air battery, the electrolyte cannot be replenished and recovered in time when the electrolyte is depleted or the battery stops working, so that its power density and energy conversion efficiency are low, and it cannot continue to supply power.

Abstract

The invention discloses a metal air fuel cell system. The system includes the following parts: a battery stack, which is formed by a plurality of individual cells in series connection; an electrolysis tank, which is used for storing an electrolytic solution; a liquid supply and recovery cycle sub-module, which is for supplying an electrolyte to the battery stack and recycling the electrolyte into the electrolysis tank; an oxygen supply circulation sub-module, which is used for controlling the air participating in reaction in the cell stack; a thermal management sub-module, which is for controlling heat alternative in the case of electrolyte overheating and low temperature electrolyte starting; and a management module, which is used for collecting individual cell information within the battery stack to control the working conditions of each sub-module. The metal air fuel cell stack system of the present invention has the advantages of high power density, high energy conversion efficiency, sustainable supply, environmental protection and energy saving.

Description

technical field [0001] The invention relates to a fuel cell system, in particular to a metal-air fuel cell system. Background technique [0002] In recent years, large-scale batteries have made successful breakthroughs in the fields of fixed power stations and electric vehicles. At the same time, due to the differentiation of user needs for product functions, products developed for different working conditions are becoming more and more perfect. Metal-air batteries are good batteries for fixed power stations and electric vehicles. Its working principle is: the negative electrode uses active solid metal (such as aluminum, zinc, magnesium, iron, aluminum alloy, etc.) Liquid, the positive electrode is a porous oxygen electrode, which is the same as the oxygen electrode of the battery. When the battery is discharged, the oxygen (air) entering the electrode from the outside will electrochemically react at the three-phase interface of the electrolyte, active agent and catalyst to...
