Air film is by Severe blockage, and air transmittability rapid drawdown, because cheap, popularization business is dexterously referred to as disposable air
Membrane electrode, if aluminium-air cell is to select this kind of air membrane electrode, need to increase air film in above-mentioned application method
Electrode 6d is arranged on housing 6a corresponding site.
Step 3) is described to include some technology deformation methods by the addition electrolyte of hole 5, such as some aluminium-air cells will
Hole 5 is deformed into the movable sealing lid on housing 6a tops, by adding electrolyte on the top of housing.
The application method of above-mentioned power supply delivery electric car also includes aluminium electrode 6b replacing：When the aluminium electrode 6b is used
It is complete, the electrolyte inside discharge housing 6a, and reinstall aluminium electrode 6b and addition according to described step 1) to step 3)
Electrolyte.
The electric storage device 2 that power supply delivery electric car of the present invention uses is disposable aluminium-air cell, in business promotion
In be referred to as a kind of " fuel cell ", so-called fuel cell is to dissolve metal in the electrolytic solution to obtain the consumption process of electric energy and regard
For a kind of special " fuel ", therefore after electric storage device 2 is discharged every time, aluminium electrode 6b this " fuel " need to be rejoined.Aluminium electricity
The process that acquisition electric energy is dissolved in pole in the electrolytic solution is the process of a consumption active ion, can produce precipitation in the electrolytic solution
Thing, the ion concentration of electrolyte is reduced, while the process that aluminium electrode dissolves in the electrolytic solution is an exothermic process, can make electrolysis
Liquid produces a small amount of dehydration, so in the application method of above-mentioned power supply delivery electric car, includes the maintenance and more of electrolyte
Change method：
1) when electrolyte produces more sediment but its ion concentration in scope of design, by the electricity inside the housing 6a
The discharge of liquid precipitate thing is solved, described electrolyte is continuing with after filtering precipitate；
2) when the ion concentration of electrolyte drops to design lower limit, the electrolyte inside discharge housing 6a, and rejoin
New electrolyte is to designing liquid level.
Although a kind of electric storage device 2 of power supply delivery electric car of the present invention is using disposable aluminium air electricity
Pond after being discharged every time, it is necessary to reinstall aluminium electrode, it is also desirable to which periodic maintenance rejoins electrolyte, but this kind of simple
Recycling of the operation with reference to electrolyte, it is possible to form power supply delivers the industrial chain of electric car, the commercial value of the industrial chain
It is that the cost based on disposable aluminium-air cell is sufficiently low, more sufficiently high than energy, the capacity of electric storage device 2 is sufficiently large,
So as to produce considerable technological value and commercial value.
Following examples are only used for further illustrating technical scheme, and these technical schemes can be used alone,
It can add or combine and use other mature technologies.

Embodiment 2
The power supply of embodiment 1 delivery electric car designed by be a kind of standard aluminium air cell product, aluminium electrode 6b
Installed when submitting user to use for the first time, it is only necessary to be added into standard in the housing 6a of each aluminium air cell
The electrolyte of design, you can to enable described electric storage device 2.But aluminium-air cell also has one kind to be used by user in first time
When the product just voluntarily installed, meanwhile, after aluminium-air cell is discharged, aluminium electrode 6b plate body 6b2 will be dissolved in electrolyte
In, it need to reinstall aluminium electrode 6b when reusing.
The present embodiment is directed to the aluminium-air cell for needing user just voluntarily to install aluminium electrode 6b when using first time, and
Aluminium electrode 6b and in use periodic maintenance electrolyte are changed when reusing or rejoins electrolyte, according to following step
It is rapid that aluminium electrode is installed, adds electrolyte with external liquid stream pump tool；Wherein, if changing aluminium electrode 6b during category use,
The electrolyte of each enclosure interior need to be discharged by being arranged on the hole 5 of housing 6a bottoms first, then according to following steps again
Aluminium electrode is installed and adds electrolyte：
The aluminium electrode 6b of 35 aluminium air cells is arranged in embeded slot 6c by step 1)；
The embeded slot 6c for having installed aluminium electrode 6b is fixed on the rib inside housing 6a by step 2)；
Step 3) adds 500 liters of electrolyte with external liquid stream pump tool by the top liquid filling hole 5 of housing；
Above step 3) there are triple implications, first, the method class that electrolyte addition, adding method and embodiment 1 are described in detail
Together；Second, filtering out sediment to the electrolyte of discharge, its ion concentration (or the estimation of measurement proportion) is measured, when the ion of electrolyte
It is continuing with when concentration is in scope of design, and supplements electrolyte horizontal (aluminium electrode reaction is except generation sediment to normal level of liquid
Outer meeting heat release, causes a small amount of dehydration)；Third, when discharging the ion concentration of electrolyte less than design lower limit, re-replace new
Electrolyte is added to design liquid level.
Embodiment 3
The liquid feeding of electrolyte described in above example 1 and embodiment 2 is to use external liquid stream instrument, the aluminium of the present embodiment
Air cell 6 is provided with special electric liquid flow pump.Electric liquid flow pump is made up of the dc motor of fluid-flow pump and disjunctor,
It is positioned close to outside the housing 6a of the top liquid filling hole 5, liquid stream efferent duct accesses housing by described top liquid filling hole 5
6a inside, described dc motor by power switch connect electric storage device 2 power output terminal (dc motor
Operating voltage needs to match with the output voltage of electric storage device 2).During described 2 liquid feeding of electric storage device, the liquid stream of electric liquid flow pump is defeated
Enter the electrolyte conservation tank that pipe connection is arranged on outside power supply delivery electric car, it is automatic by the power switch realization for closing described
Liquid feeding.
Embodiment 4
The deformation design of liquid filling hole 5 on housing 6a tops will be arranged on described in embodiment 1, hole 5 is deformed into housing 6a tops
Movable sealing lid, by movable unlimited housing 6a tops liquid feeding, hole 5 is sealed with movable sealing lid after liquid feeding；Exist in addition
Increase DC/DC equipment on the basis of embodiment 1, its function includes direct current pressure regulation and the management of voltage/current controls, power supply
Input connects the power output end of the electric storage device 2.
The power output end of the present embodiment DC/DC equipment can be the offer tune of external discharge load 4 that power supply delivers electric car
Press direct current, the power battery charging of for example, conventional riding electric automobile.
It should be noted last that the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted.Although ginseng
The present invention is described in detail according to embodiment, it will be understood by those within the art that, to the technical side of the present invention
Case is modified or equivalent substitution, and without departure from the spirit and scope of technical solution of the present invention, it all should cover in the present invention
Right among.
