Liquid pipeline built-in compact type aluminum-air fuel cell monomer

Abstract

The invention relates to an aluminum-air fuel cell monomer structure, particularly to a liquid pipeline built-in compact type aluminum-air fuel cell monomer capable of achieving built-in liquid supply through a liquid pipeline in the reaction power generation process of an aluminum-air fuel cell, so that the phenomenon of liquid connection is avoided, and the consumption rate of aluminum is reduced. The liquid pipeline built-in compact type aluminum-air fuel cell monomer comprises a shell, an aluminum electrode is arranged in the shell through an aluminum electrode holder, an inner grid is arranged on each of two opposite side surfaces of the shell, an air electrode is arranged on the outer side of each inner grid, a grid plate is arranged on the outer side of each air electrode, a seal ring is arranged between the aluminum electrode holder and the shell, the air electrode is tightly fitted with the shell, an aluminum electrode connection bar is arranged on the aluminum electrode holder, and a liquid inlet and a liquid return opening are formed in the shell, and are respectively communicated with an inner cavity of the shell through pipelines. The liquid pipeline built-in compact type aluminum-air fuel cell monomer has the advantages of reasonable structural layout, small size and compact structure, the phenomenon of liquid connection is avoided, and the consumption rate of aluminum is reduced.

Description

technical field [0001] The invention relates to a single structure of an aluminum-air fuel cell, in particular to a built-in compact liquid path that can realize liquid supply through a built-in liquid path of the aluminum-air fuel cell during the reaction power generation process to avoid the phenomenon of liquid connection and reduce the aluminum consumption rate aluminum-air fuel cell. Background technique [0002] Commonly used aluminum-air fuel cells use an external pipeline to supply liquid to the monomer when the electrolyte is supplied, which will cause the positive and negative electrodes of the front and rear batteries to conduct electricity through the electrolyte, forming a short circuit phenomenon, resulting in an increase in the internal current of the battery and additional consumption Aluminum electrodes, at the same time, because the liquid path is outside, the structure is complex and the size is large.
