Specific embodiment
In this application, in the case where not contradiction or conflict, embodiments herein, embodiment and feature can be with
It is combined with each other.In this application, conventional unit, component etc., both can be commercially available, can also be according to disclosed in the present application
Content self-control.In this application, in order to protrude the emphasis of the application, some conventional operations and unit, component are carried out
Omission, or be only briefly described.
It with unique advantage, therefore is also a kind of very potential electric energy conversion dress for fuel cell
It sets.Its energy conversion efficiency is high and is produced electricl energy with relatively lower Environmental costs.For electrical equipment, continuation of the journey is one
The point for needing to pay close attention to.Therefore, people are also highly desirable to fuel cell certainly can provide enough electric energy.Based on this demand,
People are made that effort in terms of the fuel cell of exploitation high-energy density.
Currently, common processing mode is: by multiple cell stack parallel/series, however, such mode will obviously increase
The volume of refuelling battery, so that its portability and storage property be made to substantially reduce.Therefore, the advantages of being brought by higher continuation of the journey
Thus brought disadvantage can not be covered.
In consideration of it, the solution of the high volume energy density and compressed thickness that provide fuel cell just becomes a difficulty
Topic.
After study, inventor thinks that one of main crux of the problem is: the limitation master of existing Solid-state fuel cell
If since its process conditions is limited.Wherein one of problem is, in the related technology, fuel cell is often used in production
Ceramic process, so that its thickness be made to be typically difficult to further compress.And existing fuel cell process also tends to take off
Carry out from ceramic process.
In view of the above problems, inventors herein proposing a kind of method with the problem more than evading.One of improvement of this method
It is: the forming process that the fuel of fuel cell provides each structure sheaf in the forming process and fuel cell in channel is separated.
In example, it is initially formed each structure sheaf of fuel cell, then it is handled to form fuel and provide channel.In this way,
The forming process of each structure sheaf can be made thinner in fuel cell, and can provide channel without the concern for fuel
Forming process, thus more than preferably solving the problems, such as.
Fuel cell in the application example is a kind of structure of whole solid state, and forms stacked structure/layer shape structure.Cause
This, its each structure sheaf is also solid.Further, which is also a hull cell.Change speech
It, the thickness of the battery be it is relatively thin, can satisfy special cell thickness needs.Therefore, in some examples, fuel electricity
Pond can be referred to as with full solid thin film fuel cell.
The explanation of property as an example, the thickness of the fuel cell can be restricted to micron dimension, even nanometer amount
Grade.And such thickness is for existing fuel cell, is usually to be not easy to realize.However, it should be understood that
Although technique proposed in the application example can be used for making the battery with more thin structure, according to this method
It can be used for making the bigger fuel cell of thickness.
In addition, the full solid thin film fuel cell of single layer can be made using the method provided in the application example.When
So, this method can be used for the full solid thin film fuel cell of production multilayer, such as two layers, two layers, four layers, even more
Layer.It should be pointed out that " single layer "/" two layers " etc. described herein is the primary structure with fuel cell that battery is included
The number of the battery of layer.Subsequent, the battery addressed in this way is can be referred to monocell.Therefore, the fuel cell of single layer
It can refer to the first monocell;Two layers of fuel cell can refer to including two monocells, such as the first monocell and second
Monocell.
If only needing to do the full solid thin film fuel cell of a monomer or single layer, structure such as Fig. 2 uses Fig. 1 knot
Structure excludes filler clean through oversintering.If doing multilayer, therefore all monomers can be superimposed (work in layer
Can be realized by the deposition in manufacture of semiconductor in skill), unify sintering again after the completion of laminated construction and filler is excluded to do
Only.Here example only is done by the full solid thin film fuel cell of 2 layers of monomer, the 3rd can also be done again in fact, the 4th is waited packet
Containing 3 even the multilayer full solid thin film fuel cell of the above monomer.
For generally, the method in example can produce the core component of Solid-state fuel cell such as with combination film technique
Anode, cathode and electrolyte.In addition, by combination film and etching technics, it can be by the bipolar plates portion with groove structure
Part is effective and electrode is combined together, and constitutes a complete full battery structure.
Existing conventional fuel cell, this fluted block is bipolar plates, usually steel plate or graphite plate.In useization above
The method for learning corrosion, which etches, carrys out groove structure.Then ready-made bipolar plates are buckled on the positive and negative anodes of battery, form one very
Positive individual fuel cells.So being complete different preparation method with membrane fuel cell described in the application example
And process.Because conventional fuel cell is thick, the positive and negative anodes of bipolar plates and battery can be prepared separately completely.
However, electrode material thickness is only as membrane fuel cell desired in the application example and may be implemented
There are micron or even Nano grade, therefore inventor proposes to allow the material of bipolar plates as substrate or substrate, on this substrate first
Groove structure is etched, all technique is just established to be done step by step on the substrate.Secondly because the side of chemical attack
Method is unable to reach controllable the micron even etching of Nano grade, therefore the method that reactive ion beam etching (RIBE) can be used, industrially,
The controllable micron even microstructure of Nano grade can be reached with the method that reaction particle beam etches.
The method in example will be described in detail below.
The production method of full solid thin film fuel cell in example mainly includes the steps that following referring to S101 and step
S102, and may be in the subsequent some steps selectively added being mentioned.
Step S101, assembly 100 is provided.
The assembly 100 is provided with the fuel cell of a basic structure in principle.Also, from the angle that technique is realized
For on degree, combination film technique, refering to fig. 1, assembly 100 include first the 101, first electricity of current collector layer of successively lamination arrangement
Pole layer 102, electrolyte layer 103, the second electrode lay 104 and the second current collector layer 105.
From material level, above each structure sheaf can use ceramic material, specifically can be according to actual
Selection needs to be adjusted.Illustratively, for example, first electrode layer 102 uses nickel oxide and adulterates the combination of the zirconium oxide of yttrium
Object is made.The second electrode lay 104 can be made using rare-earth base perovskite composite oxides.Wherein, rare-earth base calcium
Titanium ore composite oxides include lanthanum-strontium manganese ternary compound oxides.Electrolyte panel can using doping yttrium zirconium oxide production and
At.
Refering to fig. 1 and Fig. 2, the first current collector layer 101 have the first groove 107, the second current collector layer towards first electrode layer 102
105 have the second groove 108 towards the second electrode lay 104, and being filled in the first groove 107 and the second groove 108 can
The filler 106 being removed, to remove the filler 106 in subsequent step S102 step.
For the first current collector layer 101 and the second current collector layer 105, the two (can be based on technique using identical material
The convenience of operation considers, and the two is also possible to be made by different materials of course) production.As its name suggests, the first afflux
101/ second current collector layer 105 of layer has the ability for collecting electric current, and therefore has corresponding structure.It can be by battery
The electric current that active material (oxidized reduction reaction) generates collects, and forms current versus output macroscopically.?
Therefore, to improve or improving the ability for collecting charge, two current collector layers can usually come into full contact with active material, and internal resistance is answered
It is as small as possible to be preferred.It is considered based on such, current collector layer can be made of silicon materials used in semiconductor technology.Invention
People thinks that the electric conductivity of silicon materials (such as semiconductor silicon) is just able to satisfy the functionality of fuel cell current collection.
In order to facilitate understanding, which can obtain similar with the second current collector layer 105 in lithium ion battery
Structure show.In lithium ion battery, this is often meant that, metal foil, such as copper foil, aluminium foil.In this application, alternative
Ground, such as above-mentioned current collector layer can be silicon thin film.
For from structure, above each structure sheaf can have different thickness, specifically can be according to actual choosing
Needs are selected to be adjusted.For example, first electrode layer 102 is in stack direction with a thickness of 10~100 microns;The second electrode lay 104
In stack direction with a thickness of 10~100 microns;Electrolyte layer 103 is in stack direction with a thickness of 5~30 microns;First afflux
Layer 101 is in stack direction with a thickness of 50~200 microns;Second current collector layer 105 is in the micro- with a thickness of 50~200 of stack direction
Rice.Although here, give the thickness of each structure sheaf (substantially and functional layer), this is not intended to restriction or more
Thickness be necessary.On the contrary, each structure sheaf can have different thickness, and usually bigger thickness is to be easy to real
It applies, and smaller thickness may generally require finer and exacting terms to realize.For example, passing through choosing as above-mentioned
Selecting the thin-film technique in manufacture of semiconductor may be implemented the scale control of micron, even nanometer.It should be noted, however, that right
In micron, the micro-structure of even nanometer all solid state membrane fuel cell for, using except semiconductor technology, it is also necessary to
The processing side in channel is provided to obtain fuel by subsequent processing (the step S102 as follows referred to) in conjunction with described above
Formula.
The technique of each structure sheaf in process aspect, assembly 100 has a variety of possible selections.But generally and
Speech, the first current collector layer 101, the second current collector layer 105 can be made of etching technics or depositing operation.Generally, when the first collection
When fluid layer 101 is made by etching technics, the second current collector layer 105 usually can choose depositing operation production, and vice versa.
First electrode layer 102, second electrode and electrolyte layer 103 take depositing operation to make.Wherein, depositing operation includes that sputtering is heavy
Long-pending or pulse laser deposition.Based on such elaboration, it is recognised that assembly 100 is mainly in conjunction with increasing material and subtract the side of material
Formula is made.
As an example, the first current collector layer 101 obtains in the following manner:
First step, refering to Fig. 5, formed in the base 201 for the first material production for being used to form the first current collector layer 101
Patterned first mask 203.For example, surface coverage mask plate, the mask plate have on a silicon substrate by semiconductor technology
The figure showed in a manner of hole, through-hole, through slot etc..
Second step, refering to Fig. 5, pass through etching base/base 201 and form the first groove 107.Figure therein will be constituted
The a part in fuel offer channel.For example, making substrate by high-energy light beam guiding by the etching base of the hole of mask plate using laser
Calcination and remove some materials formed channel.It is apparent that the first mask 203 can be kept under etching condition (such as laser irradiation)
The stability of its own, i.e., will not simultaneously superlaser ablation.It is therefore contemplated that the first mask 203 is the non-of etching condition
Bright material, etching condition can only penetrate the first mask 203 at patterned area (such as groove) and be irradiated in base 201.In addition, being
Avoid etching that the figure come is different from desired shape, and therefore, etching condition, which is contemplated to be, vertically to be irradiated in base 201
It, will be on the figure " transfer " to base 201 on the first mask 203 to reach in mask plate.
Third step fills filler 106 in the first groove 107, refering to Fig. 6.
Filler 106 can choose the various substances being easily removed, and not cause because removing filler 106 to substrate
Detrimental effect.As a kind of selection, filler 106 can choose the substance for being easy to be removed by heating.
It in initial provide is mentioned with relatively thicker state (can play a supporting role) in view of base 201
For therefore, after executing the above first step to third step, can choose and handle base 201, that is, subtract come what is used
Thin base 201.It means that being carried out to it thinned when base 201 can provide a supporting role in the state of relatively thinner
The step of processing, can not need to execute.
Further, the needs for being made other structures layer in the first current collector layer 101 based on subsequent, can choose first
Mask 203 removes.The opportunity of mask removal for example can be after etching base forms the first groove 107, in the first groove
It is executed before filling filler 106 in 107 and removes the first mask 203;Alternatively, in the first groove 107 fill filler 106 it
It executes afterwards and removes the first mask 203.Since the first mask 203 does not need the surface for being particularly fixed on base 201,
It is also to be easily achieved that it, which is removed,.
Adaptably with the production method of the first above-mentioned current collector layer 101, the second collector plate can be made by the second material
It forms, accordingly the second current collector layer 105 can be obtained in the following manner (refering to Fig. 7):
Layer 202 is removed firstly, being formed in the second electrode lay 104 using the material of filler.Usually removing layer 202 can lead to
It crosses to carry out the coating method such as scratching using filler material and be formed, still, based on special thickness requirement, it may be necessary to take it
His mode, which handles filler, covers it on the second electrode with thinner thickness.
Secondly, forming patterned second mask 204 removing layer 202, it is recessed to remove the formation second of layer 202 by etching
Slot, and remove mask.
Similar with the first current collector layer 101 of aforementioned production, the second mask 204 is the opaque body of etching condition.Etch item
Part is only contacted by such as through-hole of the second mask 204, through slot structure with second electrode, and causes ablation etc. to second electrode
Role and influence.Second mask 204 can be made using material identical with the first mask 203, still, patterned
Shape, magnitude/size can be different with the first mask 203.For example, the patterned structures of the first mask 203 can be with
Multiple fillet connected in stars that first size equidistantly arranges;The patterned structures of second mask 204 can be with the second size (no
With and first size, such as larger than or be less than) multiple fillet connected in stars for equidistantly arranging.It can certainly be other layout sides
Formula, for example, multiple fillet connected in stars of the first mask 203 arrange in a first direction, multiple fillet connected in stars of the second mask 204
In second direction arrangement (vertical with first direction).
By the way that the second mask 204 removed after etching, thus make in second electrode part is removed by filler material after
Removal layer have patterned structures identical with the second mask 204.
Again, the second material is filled into the second groove in such a way that covering removes layer 202.
By previous step, removes layer 202 and form fluted i.e. the second groove 108.As a result, by the second groove 108
The second material of interior filling, the second groove 108 is filled up.It is based further on the needs such as charge transfer and cell package, the second material
Material, which can be, covers the whole for removing layer 202.Therefore, the second material not only has the part in the second groove 108,
Also there is the surface in removal layer 202 and cover the region for removing not set second groove 108 of layer 202.
When the second current collector layer 105 of the above production, the removal layer 202 mainly constituted by forming complete filler 106,
The removal for carrying out part to it again refills the making material (the second material) of the second current collector layer 105.In other examples,
It is also possible to directly make and has reeded graphical removal layer 202.For example, on the second electrode by mask covering, then again
106 material of filler is covered on mask by way of such as brushing.The mask can be the complementary mask of the second mask 204
(i.e. the two is made by same sheet material, and the hole of one is used for shape for etching removal 106 material of filler, the hole of another one
At 106 material of filler).
As a kind of further embodiment, in other examples of the application, in order to integrate more fuel cells
Structure may also comprise third electrode in assembly 100, and the third polar stack is placed in the second current collector layer 105.Show such
Example in, the second current collector layer 105 be usually with bipolar plates (channel pass fuel can be passed through in the two sides of thickness direction) by way of
It is produced and utilizes, therefore, the second current collector layer 105 has the third groove 110 away from the second electrode lay 104, and third groove
110 are occupied by filler 106.In this way, in other further examples, it is subsequent to be formed and first electrode layer 102, electricity
Solve matter layer 103, the second electrode lay 104 and the similar electrode of the second current collector layer 105, electrolyte, electrode and current collector layer structure.
In this way, such fuel cell can be equal to the cascaded structure of two batteries.In other words, the production method of assembly 100
The step of may also include production electrode, electrolyte, electrode and current collector layer structure.
First mask 203 mentioned above and a kind of the second mask 204 (can be photomask, Photomask) can be with
Using the various mask materials in existing manufacture of semiconductor, it is not particularly limited in the application.In order to be more clearly understood that
Mask in example, such as can choose metal, glass (such as quartz glass, Pyrex) production mask.Mask can be one
A structure with rectangular section can have multiple hole slots etc. for subsequent production fuel and provide channel.
Step S102, processing assembly 100 is removed to form filler 106 recessed including the first groove 107 and second
The fuel flow channel 109 of slot 108.
The mode of assembly 100 is handled there are a variety of possible selections, with specific reference to the property also assembly of filler 106
The property of each structure sheaf in 100 is chosen.For example, in a kind of optional example, when filler 106 can pass through heat treatment
Removal, and when heat treatment is not sufficient to damage each structure sheaf (such as the first current collector layer 101), can choose heating assembly
100.Therefore, the method that processing assembly 100 is removed filler 106 includes: that heating assembly 100 keeps filler 106 logical
The mode for crossing burning or gasification disappears.
In some examples above-mentioned, the first current collector layer 101 and the second current collector layer 105 are silicon materials, and first electrode
Layer 102, the second electrode lay 104 and electrolyte layer 103 are ceramic materials, and filler 106 is that colloid has polystyrene
When, it can choose heating assembly 100.The temperature of heating can be 1000 DEG C, heating time be 2 hours, colloid is heated
It vapors away.Filler 106 can also be other high molecular materials such as polypropylene, polyethylene etc. resin material.This is understood that
It is handled for assembly 100 by sintering process, eliminates filler 106, and each structure sheaf of ceramic material is made to combine closely
And reinforcing.
It, can be to the control that its heating method is more refined, for example, heating group corresponding to the scheme of the heat treatment
The mode of zoarium 100 includes: to heat assembly 100 to filler 106 by way of gradient increased temperature to disappear.By to heating side
The selection of formula may make it easier for removing for certain 106 material of filler, while may also be ensured that in assembly 100
Other structures layer more firmly combine.
Further, after heating, based on test, use need to cool down it, therefore, in filler 106
After disappearance, it can choose by the cooling assembly 100 of gradient cooling mode, to make assembly 100 not occur feelings of such as chapping
Condition.Certainly, the heat treatment of assembly 100 can be to be placed directly in the container (such as furnace) such as 1000 DEG C and directly adds
Heat, then air cooling or furnace cooling.
In addition to above-mentioned heat treatment, or filler 106 can also be made to remove by such as chemically reacting, such as pass through illumination
It reacts it and disappears or remove filler 106 by other chemical reactions.But, it is contemplated that it is each in assembly 100
It can be in conjunction with more firm, therefore, if filler 106 cannot be removed by temperature appropriate by heat treatment between a structure sheaf
In the case where (can not still eliminate on temperature of each structure sheaf by high temperature), can first be heat-treated assembly 100 makes
Each structure sheaf combines, and then handles filler 106 in the corresponding mode of use and removes it.
It is explained above and removes filler 106 by the modes such as being heat-treated, chemically reacting, still, it is not excluded that pass through machine
Tool mode removes filler 106.For example, filler 106 can be used magnetisable material production, pass through when needing to remove it
As magnet absorption and remove filler 106.Alternatively, using atomic small (less than the width of the first groove 107 and the second groove 108
Degree) probe, filler 106 is removed in a manner of puncture, extruding, dragging etc..
Alternatively, the mode of removal filler 106, which is also possible to chemical reaction, combines mode with mechanical treatment.For example, logical
Crossing chemical reaction makes filler 106 change and the contact jail between groove (such as the first groove 107 and the second groove 108)
Gu degree decline even loosens filler 106, so as to remove filler 106 by various mechanical systems appropriate.
In addition, first electrode and second electrode described above can be cathode, anode respectively, naturally it is also possible to be point
It is not anode, cathode.
Corresponding to above-mentioned process, a kind of full solid thin film fuel cell is obtained in example.
In a kind of embodiment, which substantially can be first monocell.It is in thickness
(stack direction) reaches micro-meter scale or nanoscale.First monocell includes the first collector plate that successively lamination is arranged, anode
Plate, electrolyte panel, cathode plate layer and the second collector plate.
First groove is arranged towards anode plate in first collector plate, and second groove is arranged towards cathode plate in the second collector plate, the
One groove and second groove are configured to conveying fuel.
Wherein, the first collector plate and the second collector plate are made using semiconductor silicon material, anode plate (e.g., zinc oxide/
Stable zirconium oxide/the YSZ of ZnO+ yttrium), electrolyte panel (such as YSZ) and cathode plate (such as LaSrMnOx/ lanthanum strontium manganese oxygen or strontium manganate
Lanthanum) it is formed using ceramic material.Anode plate can be made using the composition of nickel oxide and the zirconium oxide for adulterating yttrium;
Alternatively, electrolyte panel is made using the zirconium oxide of doping yttrium;Alternatively, cathode plate layer uses rare earth based perovskite combined oxidation
Object is made, wherein rare-earth base perovskite composite oxides include lanthanum-strontium manganese ternary compound oxides.
For the thickness of the first monocell, and following effect can be realized by the reasonable selection of above-mentioned technique: sun
Pole plate is in stack direction with a thickness of 10~100 microns;Alternatively, electrolyte panel is in stack direction with a thickness of 5~30 microns;Or
Person, cathode plate is in stack direction with a thickness of 10~100 microns;Alternatively, first collector plate stack direction with a thickness of 50~
200 microns;Alternatively, the second collector plate is in stack direction with a thickness of 50~200 microns.
Further, in other examples, full solid thin film fuel cell may include two single-cell structures, if any preceding
The first monocell and following the second monocells 115 that will be mentioned stated (refering to Fig. 4).First monocell and the second monocell
115 can be integrated in micron and nanoscale similar to concatenated mode.Certainly, in other examples, full solid thin film fuel
Battery also may include the monocell of three to become one or four or five or more.It below will be by first single electricity
It is illustrated for the battery (following to be referred to by bilayer cells generation) that pond and the second monocell 115 are constituted.
Bilayer cells include stacked first monocell and second monocell 115.For multi-layer cell,
It will include multiple second monocells 115.
In bilayer cells, the first monocell can be made to be adaptively adjusted as follows, so that it matches with the second monocell 115
It closes.For example, the second collector plate of the first monocell has third groove (in other words, the second afflux away from the second groove
Plate has two surface/top surface and bottom surface grooves --- second groove and the third groove for being distributed in thickness direction).
For two layers of battery in multi-layer cell comprising lamination is arranged in one second list on the first monocell
Battery 115.Second monocell 115 includes second plate plate 111, the second electrolyte panel 112, the second cathode plate 113 and third
Collector plate 114, third collector plate 114 have the 4th groove arranged towards the second cathode.Structure shown in Fig. 3 is as bilayer
And a front layer of above three layers or more of fuel cell structure is provided, complete battery structure is based on its subsequent production shape
At.In Fig. 3, schematic structure includes one layer of monocell and the structure sheaf being formed thereon composition.Wherein, one layer of monocell is by
One current collector layer, 101 to the second current collector layer 105 (having upper and lower two grooves) is constituted;" structure sheaf being formed thereon " includes second
Anode 111.Hole (such as the first groove 107) is formd with each current collector layer although showing it in Fig. 3, for
For one complete full solid thin film fuel cell with expected the number of plies (such as 1,2,3), the formation of hole is complete
After portion structure sheaf/functional layer stacking completes, constructed by the filler in sintering removal hole.
For three layers in multi-layer cell and the above battery, with third collection between two neighboring second monocell 115
The mode that flowing plate 114 and second plate plate 111 contact is stacked, and the third afflux being held between the second cathode and second plate
Plate 114 is provided with the 5th groove, and the 5th groove deviates from the 4th trench layouts.
For example, as a kind of explanation being more readily understood, when the quantity of the second monocell 115 is one, second single electricity
Pond 115 is incorporated in the second collector plate of the first monocell with second plate plate 111, and the third groove of the second collector plate is towards
The third collector plate 114 of the second plate plate 111 of two monocells 115, second monocell has the monocell towards second
4th groove of the second cathode plate 113 setting.
When the quantity of the second monocell 115 is two and is denoted as the first bottom cell and the first top cell respectively, the
One bottom cell and the first top cell contact stacked, the first bottom list of contact with second plate plate 111 with third collector plate 114
