Embodiment
As shown in Figure 1, a kind of boron fuel battery, cathode collector net 1, porous cathode plate 2, yin including stacking gradually connection
Electrode catalyst layer 3, solid oxide electrolysis matter layer 4, anode catalyst layer 5, porous anode plate 6, anode current collector net 7, wherein solid
State oxide electrolyte layer 4 is the two-electrolyte layer that borate and solid-oxide mix.
Battery production method is as follows:
1) porous cathode plate 2, cathode catalyst layer 3, solid oxide electrolysis matter 4, anode catalyst layer 5 and porous anode
Plate 6 is solid oxidizer fuel cell, is placed in ceramic tube 11.When placement, 2 side of porous cathode plate is to outer, porous anode plate 6
In lateral, and cathode collector net 1 is placed on the outside of porous cathode plate 1, and draw cathode leg 12, while in porous anode plate 6
Currect collecting net 7 is placed in outside, and draws anode tap 8；
2) boron bisque 10 is placed outside anode current collector net 7, is placed boric acid salt deposit 9 outside boron bisque 10, is completed boron fuel battery
Installation.
3) the boron fuel battery being completed is put into heating furnace, is heated to predetermined temperature, kept the temperature 10-30 minutes, make
Boron salt layer 9 is in a molten state, this is because gravity and capillarity, the boron salt layer 9 of melting can be infiltrated to boron bisque 10, reaches
Porous anode layer reaches solid-state electrolyte layer through anode layer hole.Under anode catalyst effect, boron simple substance loses electronics,
Boron ion is formed, the electronics lost reaches porous cathode layer by external circuit, and the oxygen in air passes through porous cathode at this time
Layer is followed by being formed oxonium ion by electronics by cathode catalyst layer catalysis, and oxonium ion penetrates solid oxide electrolysis matter layer and reaches more
Hole anode layer is reacted with boron ion, generates boron oxide.
In the present embodiment, boron powder is pure boron powder, and unformed boron powder and crystallization boron powder, preferably unformed boron powder can be used.
This is because unformed boron powder structural disorder, there are a large amount of defects for inside, therefore thermal stability is poor, it is prone to react, have
Help to be promoted boron fuel battery performance, and crystalline state it is intact boron powder internal flaw it is few, boron powder thermal stability is high, is unfavorable for anti-
The progress answered.
Between 6-52 μm, the excessive then reaction of partial size not exclusively, causes reaction efficiency to reduce, causes to fire boron powder size controlling
Material waste, excessive additionally, due to partial size, boron particles specific surface area is small, and activity reduces, therefore is unfavorable for reaction and carries out, battery performance
Decline.Boron powder diameter is too small, and boron powder specific surface area is caused to improve, and activity increases, and reaction speed is accelerated, and is unfavorable for reaction controlling,
Simultaneously because active enlarged surface caused by boron powder is too small is easy to appear oxide, protective layer is formed on boron powder surface, completely cuts off boron
Powder is contacted with the external world, causes to react slack-off.
Boron salt layer is mainly Boratex, potassium borate and aluminum oxide, wherein Boratex 46-62wt%, potassium borate 18-
32wt%, aluminum oxide 6-36%；Aluminum oxide plays the role of diluent, avoids borate concentration excessively high, therefore contain
Amount control is between 6-36%.Boratex and potassium borate matching ratio influence the fusing point of the two mixture, both control matching ratio
Example helps to adjust mixture fusing point, by the control of cell reaction temperature between zone of reasonableness.If cell reaction temperature mistake
Height causes cell reaction too fast, it is difficult to control；If cell reaction temperature is too low, reaction is not easy to carry out, under battery efficiency
Drop.In addition reaction temperature is too low, then influences the ability of solid electrolyte transmission payload.Therefore the two matching ratio need to be adjusted, it will
Cell reaction temperature controls between 650-1100 DEG C.
Solid-oxide galvanic anode is porous NiO-YSZ plate, and plasma beam physics is used on porous anode plate
The ZrO2 (YSZ) of the method for vapor deposition or electro beam physics vapour deposition deposition Y2O3 doping forms 2-280 micron thickness
Electrolyte layer, cathode be La0.85Sr0.15MnO3 plate, wherein by taking electro beam physics vapour deposition technological parameter as an example: will
Porous anode plate is put into the cavity of electro beam physics depositing device, is then vacuumized, vacuum degree 0.01-0.1Pa, by temperature
It is increased to 700-900 DEG C, galvanization 1.0-2.0A, it is uniform for deposition surface layer, by sample with revolving speed 5-30rpm, deposition process
After, sample is cooled to room temperature, takes out sample.Plasma beam physical vapour deposition (PVD) can be used or electron beam physical vapor is heavy
Product, forms equally distributed columnar structure in anode surface, transmits the directed access to be formed perpendicular to pole plate for oxonium ion, can drop
The passing time of hypoxemia ion improves the working efficiency of entire boron fuel battery.
