Open type metal-air fuel cell system capable of uninterruptedly supplying power

Abstract

The invention discloses an open type metal-air fuel cell system capable of uninterruptedly supplying power, which relates to the field of metal-air fuel cell packs and comprises a sensing subsystem, acontroller, a circulating filtration subsystem, an electrolyte tank and a plurality of open type metal-air fuel cell monomers, wherein the open type metal air fuel cell monomers are sequentially arranged in the electrolyte tank, and the open type metal air fuel cell monomers are connected in parallel; the air electrode of the open type metal air fuel cell monomer is of a groove body structure, and the concave surface of the groove body structure is upward; the sensing subsystem is placed in the electrolyte tank; the electrolyte tank is communicated with the circulating filtration subsystem; and the controller is used for controlling the circulating flow of the circulating filtration subsystem according to the electrolyte temperature information acquired by the sensing subsystem. Accordingto the open type metal-air fuel cell system, a sealing structure is omitted, the metal electrode of the cell can be replaced during uninterrupted power supply, and maintenance of the metal-air fuel cell is greatly simplified.

Description

technical field [0001] The invention relates to the field of metal-air fuel cell stacks, in particular to an open metal-air fuel cell system capable of uninterrupted power supply. Background technique [0002] As a power battery widely used at present, the lithium-ion battery pack has the characteristics of high power density and long cycle life, and is widely used in power equipment. However, lithium-ion batteries also have their inherent defects. First, the energy density is low. In the field of electric vehicles that widely use lithium-ion batteries as energy sources, the low energy density of lithium-ion batteries has caused the cruising range of pure electric vehicles to be unsatisfactory; The second is that lithium-ion batteries have high requirements for charging and discharging temperatures. The general requirement is that below 0°C, they cannot be charged, and below -10°C, they cannot work, which causes great inconvenience to the use in cold regions in winter. At t...
