Description

A kind of chargeable zinc/air fuel cell

Technical field

This utility model is related to water battery technical field, more particularly, to a kind of chargeable zinc/air fuel cell.

Background technology

With people to the understanding of environmental protection and pursuit, global scientist is making substantial amounts of opening for eco-friendly power source Send out and research.Supply of electric power source now, sends out including solar electrical energy generation, wind-power electricity generation, hydroelectric generation, tidal power generation, underground heat Electricity, thermal power generation and nuclear energy power generation.At present, thermal power generation and nuclear energy power generation are mainly to provide society stable electric energy supply Source；However, thermal power generation and nuclear energy power generation have serious environmental pollution and the low problem of conversion efficiency, and solar energy is sent out The ability for stable power-supplying in technology and equipment such as electricity, wind-power electricity generation, hydroelectric generation, tidal power generation or geothermal power generation also Need to break through.Therefore, be converted to the fuel cell of electric power with chemical energy, gradually show up prominently.

Fuel cell is a kind of electric supply installation that the chemical energy of fuel is directly converted to electric energy, is similar to a kind of small power generation Stand, the assembly of composition fuel cell is minimum to need battery body, two electrodes (electrode), electrolyte, electrolytic thin-membranes (electrolyte membrane) and/or current collector (current collector) etc..In simple terms, electrode is fuel oxygen Change the place with the electrochemical reaction generation of oxidant reduction, or the diffusion media of anode chemical fuel, and electrode is general Anode (Anode) electrode and negative electrode (Cathode) electrode two parts can be divided into；And the function of electrolyte is to separate oxidant and go back Former dose and proton conducting simultaneously.Additionally, current collector is also referred to as bipolar plates (bipolar plate), it has collected current, dredges The effect led reacting gas and separate oxidant and reducing agent.

For metal air fuel cell (abbreviation metal-air battery) with metal and oxygen as fuel, it is by metal The diffusion oxygen being imported with air pole carries out oxidation reaction, and produce electric energy after generate simultaneously metal-oxide, hydrogen and/ Or water.The electrochemical reaction being oxygen and metal due to the operation principles of metal-air battery, it has high performance price ratio Characteristic, so be subject to the suitable attention of personal electric consumption market.

The R＆D direction of common metal air cell manufacturer is conceived to how quickly and easily to carry out battery recycling and profit again With, therefore the design form of its product to carry out group to a plurality of metal-air batteries nothing more than the housing accessory being transmission complexity Dress, and consumer also also needs to start or close the running of metal-air battery product by extra control computer. Problem deserving of attention is, complicated housing accessory and extra control computer not only can make the life of metal-air battery product Produce high cost, and can make metal-air battery product that consumer cannot be allowed to carry with.

Meanwhile, for the internal structure of metal-air battery, manufacturer in order to obtain preferably packaging effect and safety, because And increased complexity packaging mechanism, result in battery volume increase and cannot rapid disassembling or recovery, and if contact or simultaneously Join multiple fuel cells, or formed along with other fuel tanks hybrid power mechanism when, its device is packaged Also lifted therewith with the difficulty of disassembly ＆ recycling.If additionally, battery run out of gas in addition it is also necessary to be passed to battery design manufacturer or It is the maintenance manufacturer of battery, more loaded down with trivial details step is dismantled and encapsulates with complexity again, more cause manpower and machine cost Increase.

From the foregoing, it will be observed that the complicated packaging mechanism of metal-air battery makes to run out of gas, battery has economic worth reaction Metal (oxidized metal) afterwards is not easy to remove, battery body or shell mechanism also cannot recycling, cause the pole of resource Big waste.

Therefore, for the above, need prior art is reasonably improved.
