Compared with the prior art, the metal air fuel cell has the advantages of easiness in removal of the anode precipitate, relatively long maintenance period and relatively low using cost.
Description
Technical field
The utility model relates to field of batteries, particularly a kind of metal air fuel cell.
Background technology
Traditional fossil energy not only resource reserve is limited, and in use brings a large amount of emissions, and this makes energy shortage and environmental pollution is that current social develops the two large outstanding problems that face.One of solution is exactly development of new alternative fuel.As electric power such as the water energy of clean energy resource, wind energy, solar energy, be difficult to directly on electrical appliance, directly use, need to as carrier, could use through energy storage material, so development of new battery becomes the key that new forms of energy develop.
Metal air fuel cell be a kind of with active metal as the battery of fuel, because it has very high energy density and specific power, lower cost, to advantages such as environment nontoxic pollution-frees, is considered to " green energy resource geared to the 21st century ".Metal-air cell take active metal if lithium, calcium, magnesium, aluminium, iron, zinc etc. are the active material of positive electrode of battery, active material of cathode take airborne oxygen as battery, mainly with alkalescence or neutral aqueous solution, be electrolyte, in discharge process, generate corresponding metal hydroxides.These hydroxide come off from surface of metal electrode with sedimentary form in electrolyte, are settled down to battery bottom.Scavenger precipitation thing when current technology is passed through periodic replacement electrolyte.Because metal anode and the air cathode distance of metal-air cell can not be too far away, in most cases, gap between anode and negative electrode is smaller, if the precipitation of hydroxide that surface of metal electrode produces comes off from electrode surface not in time, but continue below the precipitate particles of electrode surface growth or generation is too much deposited in metal anode and air cathode, the as easy as rolling off a log internal short-circuit of battery that causes, affects battery supplying power for outside.This makes the electrolyte replacement cycle of metal current air cell shorter, and the maintenance cost that causes battery to use is higher.
Summary of the invention
For the technical problem of above-mentioned existing metal-air cell, the utility model provides a kind of anodic deposition thing to be easy to length and the lower metal air fuel cell of use cost of eliminating, maintenance period.
The technical scheme that the utility model solves the problems of the technologies described above is: comprise housing, positive electrode cap, negative pole cap, as the metal electrode of anode, as air electrode and the electrolyte cavities of negative electrode, the dividing plate of perforate in the middle of being provided with in described housing, described dividing plate is divided into upper and lower two parts by housing; Described metal electrode is inverted cone-shaped and is located at housing top, and case top is fixed in the upper end of described metal electrode, and positive electrode cap is directly connected with metal electrode, and the lower end of described metal electrode is relative with dividing plate perforate; It is relative with the metal electrode conical surface that described air electrode is correspondingly conical surface shape, and the upper end of air electrode is connected with the negative pole cap of case top, and lower end is connected with dividing plate; In described housing upper portion side wall, offer multiple pores, case top is established electrolyte filling mouth, and described housing bottom is established leakage fluid dram.
In the above-mentioned metal air fuel cell with cone-shaped metal anode, described metal electrode is metal or metal alloy.
In the above-mentioned metal air fuel cell with cone-shaped metal anode, described air electrode comprises current collector layers and catalyst layer.
Owing to adopting technique scheme, the beneficial effects of the utility model are: the utility model adopts pyramidal structure, and the space that metal electrode and air electrode form is long and narrow, is convenient to anodic deposition thing and drops; The lower electrolyte cavities of lower housing portion, can store the reaction precipitation thing of peeling off from electrode surface in a large number under Action of Gravity Field, thereby avoid the deposit buildup of anode surface, the same large buffer memory of electrolyte cavities at present can improve the stability of battery and extend the maintenance period of battery, thereby reduces use cost; Leakage fluid dram can guarantee the timely eliminating of sediment and waste electrolyte, prevents from that sediment is deposited between anode and negative electrode to cause battery short circuit.
