Liquid path built-in compact aluminium-air fuel cell stack

Abstract

The invention relates to an aluminium-air fuel cell stack structure, and in particular relates to a liquid path built-in compact aluminium-air fuel cell stack. The liquid path built-in compact aluminium-air fuel cell stack comprises a tray; a cell monomer set is arranged over the tray; a front end plate and a rear end plate are arranged at the front and rear ends of the cell monomer set; a lacing wire is arranged in a manner of penetrating the front end plate, the cell monomer set and the rear end plate; a liquid inlet interface and a liquid return interface are arranged on the front end plate; an electrode lead-out interface is arranged on the rear end plate; liquid inlets and liquid return holes are arranged on cell monomers; the liquid inlets and the liquid return holes on the cell monomers in the cell monomer set are respectively connected, such that two closed passageways are formed; the liquid inlets and the liquid return holes of the cell monomers near the front end plate are respectively communicated with the liquid inlet interface and the liquid return interface on the front end plate; and the liquid inlets and the liquid return holes of the cell monomers near the rear end plate are each provided with a liquid path seal head. The liquid path built-in compact aluminium-air fuel cell stack disclosed by the invention has the advantages of being reasonable in structural layout, small in volume, compact in structure and convenient to use, replace and maintain; the liquid sticky phenomenon is avoided; and aluminium consumption rate is reduced.

Description

technical field [0001] The invention relates to an aluminum-air fuel cell stack structure device, specifically a built-in liquid circuit that can realize the liquid supply through the built-in liquid circuit of the aluminum-air fuel cell during the reaction power generation process so as to avoid the phenomenon of liquid connection and reduce the aluminum consumption rate Compact aluminum-air fuel cell stack. Background technique [0002] When the commonly used aluminum-air fuel cell is supplied with electrolyte, a main pipe is used to supply liquid to 36 monomers at the same time through an external pipeline. This will cause the positive and negative electrodes of the front and rear batteries to conduct electricity through the electrolyte, forming a short circuit, causing the battery The internal current increases, which consumes additional aluminum electrodes. At the same time, because the liquid circuit is outside, the structure is complex, large in size, and heavy in wei...

[0002] When the commonly used aluminum-air fuel cell is supplied with electrolyte, a main pipe is used to supply liquid to 36 monomers at the same time through an external pipeline. This will cause the positive and negative electrodes of the front and rear batteries to conduct electricity through the electrolyte, forming a short circuit, causing the battery The internal current increases, which consumes additional aluminum electrodes. At the same time, because the liquid circuit is outside, the structure is complicated, the size is large, and the weight is heavy.
