Description

Technical Field

[0001] The utility model relates to the technical field of metal fuel cells, in particular to a double-connected metal fuel cell monomer. Background Art

[0002] Metal fuel cells, also known as metal-air batteries, use the reaction between metal fuel plates and oxygen to form a continuous power generation device. Metal fuel cells have the advantages of low cost, non-toxicity, no pollution, and high specific energy. The main components of metal fuel cells include metal fuel plates and air membranes. Different types of metal fuel plates will result in different voltage platforms for metal fuel cells. When metal fuel cells output electrical energy to the outside, they need to be presented in the form of battery cells.

[0003] Currently, there are relatively few metal fuel cell monomers on the market, and most of them are single-group structural units. When making battery modules, multiple groups of units need to be connected in series or in parallel. This requires many additional structures, is large in size, has a relatively high product weight, and has a low module specific energy.

[0004] Therefore, it is necessary to provide a dual-connected metal fuel cell monomer to solve the above technical problems. Utility Model Content

[0012] In one embodiment, the aluminum plate of the negative electrode comprises a negative electrode plug-in that can be connected to the positive electrode plug-in of the dual-connected fuel cell stack itself.

[0013] The beneficial effects of the utility model are as follows:
