Technical field
The present invention relates to a kind of cell art, particularly relate to a kind of negative electrode bag for metal air fuel cell and application thereof.
Background technology
The world today, new renewable energy resources technology development, regenerative resource and developmental technology of new energy resources are applied to various field at leisure; Under the impact of global warming, new field of renewable energy slowly will become the leading of future source of energy field.And new renewable energy resources technology is in fuel cell field also in progressively developing, and the capacity of battery is also developed to Large Copacity at leisure by low capacity.
Current, Proton Exchange Membrane Fuel Cells (PEMFC) and direct methanol fuel cell (DMFC) have been commercially produced and have used, but its price really remains high always; In addition the research and development of the fuel cell such as Solid Oxide Fuel Cell (SOFC) and molten carbonate fuel cell (MCFC) have reached the adaptable stage.Because Proton Exchange Membrane Fuel Cells and direct methanol fuel cell will use platinum (Pt) as catalysis material, therefore want to reduce costs that production still acquires a certain degree of difficulty.
The negative electrode of existing metal air fuel cell is all the form adopting metallic plate, in order to expand response area, mostly all takes to carry out concavo-convex processing in metal surface or carry out enlarged surface in the mode of metallic plate increase pore amassing.But this kind of metallic cathode plate form has very large defect, reason is the sediment that can produce metal hydroxides or metal oxide after metal carries out oxidation reaction, they can attach at leisure and cause shorten anode life on anode, particularly the sediment viscosity that produces after oxidation reaction of magnesium air fuel cell is very high, and it attaches after on anode pile and is extremely difficult to cleaning.Its electrolyte major part of existing metal air fuel cell all uses NaOH (NaOH) or potassium hydroxide (KOH), particularly magnesium air fuel cell, and its electrolyte major part is all use salt solution (NaCl) etc.; Aluminium or zinc/air fuel cell use NaOH (NaOH) strong base solution or potassium hydroxide (KOH) etc. as electrolyte mostly, and generally its temperature when there is oxidation reaction can rise and can produce a large amount of hydrogen (H 2), and in order to prevent hydrogen (H 2) therefore to add the inhibitor suppressing hydrogen to produce in addition, so general aluminium or zinc/air fuel cell not only use the strong base solution carrying inconvenience also will consider safety problem as electrolyte.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, and providing one only needs water as electrolyte, and high-performance, the negative electrode bag for metal air fuel cell that is convenient for changing.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of negative electrode bag for metal air fuel cell, and described negative electrode bag is that its content comprises the component of following mass percent with nonwoven fabrics as lapping:
Preferably, its content comprises the component of following mass percent:
Further, in order to make powdery electrolyte be dissolved in the water fully, with the addition of carboxymethyl cellulose (CMC) in described nonwoven fabrics, accounting for the 1-2% of nonwoven fabrics gross mass.
Further, in order to improve the performance of negative electrode bag, in described nonwoven fabrics, with the addition of cerium hydroxide, accounting for 0.1% of nonwoven fabrics gross mass.
Preferably, in order to strengthen the water absorbing capacity of nonwoven fabrics, described nonwoven fabrics is made up of one or more materials in PP, PE and PET.
Further, described mixed metal powder or metal alloy are aluminium, magnesium mixed-powder or almag.Preferably, when adopting aluminium, magnesium mixed-powder, mass ratio is aluminium: magnesium=(0.5-3): (6-8); Preferably 2:8.
Further, described powdery electrolyte is NaCl or KCl or NaOH or KOH, is preferably KCl.
Preferably, described hydrogen inhibitor is potassium sulfide, temperature can be able to be controlled within 60 DEG C.
Another object of the present invention is to the application that a kind of negative electrode bag for metal air fuel cell is provided, negative electrode bag is inserted in anode, reinject water, and after 3-5 second, water is absorbed by nonwoven fabrics, causes metal air fuel cell inside chemical reaction occurs thus produces electric energy.
The Making programme of negative electrode bag of the present invention adds content after first putting into cathode terminal in negative electrode bag, namely can be made into after finally sealing with nonwoven fabrics target bag again.
Advantage of the present invention and beneficial effect are: (1) the present invention does not use high price platinum (Pt) as catalysis medium, and use and greatly reduce its production cost than the metal of its cheapness and metal oxide as catalysis medium.(2) the present invention use HHT higher high tensile water suction nonwoven fabrics its can reduce negative electrode generation oxidation reaction to greatest extent after the sediment that produces attach to anode.(3) form of metallic cathode powder bag is adopted, easy to carry, as long as provide water just can carry out reaction produce electric energy in any place, and function admirable.
