Description
Technical field
The present invention relates to a kind of solid oxide fuel cell, and in particular to a kind of air distributor of SOFC battery pile.
Background technique
Fuel cell is a kind of generating equipment that reactant chemical energy is converted into electric energy.As a kind of efficient, clear
Clean and stable performance energy technology, great advantage is to avoid combustion process directly for fuel compared with traditional power generation type
Chemical energy be converted into output electric energy, energy conversion efficiency is not limited by " Carnot cycle ".
Solid oxide fuel cell (SOFC) is most one of the type of some commercial potential in all multiple fuel cells, master
Wanting advantage includes: the fuel service efficiency with up to 50~60%, and product is mainly the waste heat of water and high-quality, to waste heat
Secondary use gross efficiency may be up to 80% or more；Output power, runs smoothly and noiseless；Fuel source is flexible, not only fits
For hydrogen, carbon monoxide, it is also applied for a variety of renewable carbon hydrogen fuels such as natural gas, coal gas and biogas；Low greenhouse
Gas discharge；The problems such as leakage, corrosion is not present in all solid state component, and is easy to modularization assembling；Without using high price catalyst
Material, advantage of lower cost.
SOFC battery pile mainly includes plate and two kinds of Basic Designs of cast and corresponding a variety of evolutions at present
Design.Wherein tubular type SOFC pile design has stable structure firm, do not need the outstanding advantages such as complicated elevated-temperature seal and by
Extensive concern.The tube type design of Siemens Westinghouse Power Corp., the U.S. is current most representative more mature design, cast
SOFC battery unit is a structure open at one end closed at one end, thin by three layers of cathode-electrolyte-anode respectively from inside to outside
The ceramic tube of film composition, is a kind of typical cathode support type structural design scheme.Air flows on the inside of ceramic tube, fuel gas
Body supply is distributed on the outside of piping unit, this is primarily due to: on the one hand, in a fuel cell, air is not only reactant (oxygen
Gas) main source and pile heat transfer main carriers, it largely influences electrochemical reaction, the temperature of SOFC
Degree, stress, physical property distribution influence pile overall work performance and service life, therefore the design of air distributor is tubular type SOFC electricity
Heap matter of utmost importance to be solved；And on the other hand, since reactant (oxygen) aerial volume fraction only has 21%, simultaneously
The air utilization ratio of SOFC pile also only has 30% or so (fuel is generally up to 80% or more), therefore the molecular mass in pile
Biggish air often has very high flow compared to the lesser fuel of molecular mass.It is experimentally confirmed that using empty on the outside of pipeline
The mode of gas distribution has larger difficulty, and unreasonable design often leads to air as reactant and thermotransport carrier in battery
(heap level) and battery unit pipe surface distribute (battery unit level) extremely non-uniform phenomenon between unit, this will substantially
Degree reduces battery performance and service life.Therefore, the air generally on the inside of ceramic tube is distributed for the air of tubular type SOFC pile at present
Be allocated by battery unit inside pipeline, thus between guaranteeing ceramic tube cells unit and battery unit cathode-side surface compared with
Good air distributing uniformity.And such ceramic tube inside air method of salary distribution is corresponding, inevitable requirement SOFC unit is using yin
Pole is in the cathode support type design of insides of pipes.
However be pointed out that using cathode support type tubular type SOFC design between solving tubular SOFC unit and
While element cell superficial air evenly distributed this matter of utmost importance of degree, but also cathode support type tube designs are brought into simultaneously
A series of unfavorable factors, this largely reduces tubular type Performance data: i) thickness of supporting element cathode is excessive causes
Concentration difference loss in the heavier oxygen molecule diffusion process of molecular weight is excessive；Ii) since in the case where aoxidizing atmosphere, cathode is generally used
The lower ceramic material of the conductivity such as LSM is as electronic conduction medium, the very long electric current collection path of insides of pipes in addition, because
This tubular type cathode support means very high ohmic loss；Iii) fuel (especially wet hydrogen fuel) is on the outside of tubular cells unit
When distribution, flow path resistance is too small, and to easily lead to fuel utilization rate too low；Iv) air flow resistance high in pipeline will lead to
The output of required additional pump power is lost, while aggravating the pressure difference of air side and hydrogen gas side, increases the risk of air leakage；v)
Since air has very high flow value compared to fuel, high-speed air fluid will aggravate cavitation in pipeline, simultaneously
Air is the main carriers of heat again, and the peeling of electric current collection coating between interior connector is managed in aggravation by this.
Obvious, tubular type SOFC pile such as uses the design of anode support type ceramics pipe unit (to distribute in air hose, cartridge
Outside distribution) it can effectively solve the problems, such as that above-mentioned some column are secondary, however as without reasonable pipeline outside air distribution design
Mating, between severe battery unit and the air distribution results of battery surface will lead to even more serious operation of fuel cells effect
Fruit.

Many disadvantages of tubular type SOFC pile based on cathode support type, the advantage of anode support type tubular type SOFC structure of the present invention is such as
Under:
Concentration difference loses advantage: the anode support structure of battery pipe unit is distributed in insides of pipes, and outside is relatively thin cathode,
It is lost to significantly reduce oxygen in the concentration difference of cathode；
Ohmic loss advantage: since anode is mainly using metallic particles as conducting medium under reducing atmosphere, electronic conductance
Rate is substantially better than cathode, and tubular cells unit inside electrode has the shortcomings that long electric current collection path in addition, therefore anode is made
It is on the inside of tubular cells for supporting layer, cathode configures more flexible electric current collection part on the outside, ohm can be greatly lowered
Loss；
Fuel (especially wet hydrogen fuel) passes through battery unit pipe transmitted inwards, it is ensured that the flow velocity and flow resistance of fuel
And then increase substantially the fuel availability of tubular type SOFC pile；

Specific embodiment
Technical solution of the present invention is described in detail below, but protection scope of the present invention is not limited to the implementation
Example.
Embodiment: a kind of air distributor for anode support type tubular type SOFC battery pile, as shown in Figure 1, 2, mainly
Component is a hollow sprue distributor box 3, as shown in figure 3, the setting length of sprue distributor box 3, height, thick direction are respectively
X, Y, Z-direction.Several holes are reserved on former and later two faces of sprue distributor box 3 for anode support type SOFC battery pipe unit 1
It corresponds to across and is fitted close, so that SOFC battery pipe unit 1 is arranged in array on the surface of sprue distributor box 3, simultaneously
3 inner space of sprue distributor box is capable of forming the channel for air circulation around SOFC battery pipe unit 1.Specifically,
Each anode support type SOFC battery pipe unit 1 includes anode support, electrolyte layer and cathode layer from the inside to the outside, SOFC electricity
It is fuel flow channel in pond pipe unit 1, and pipe peripheral air flow passage area.
The bottom left of sprue distributor box 3 is equipped with 4 air intakes arranged along Z-direction, and 4 air intakes are all located at
1 region of SOFC battery pipe unit is with a left side.As shown in figure 4, being equipped with the sky extended along Z-direction in the lower section of air intake
Gas entrance is responsible for 2-1, and the direction of sprue distributor box 3 is entered along air stream, and the caliber of air intake supervisor 2-1 is gradually reduced,
Therefore pipeline section is tapered.The equidistant master for being connected with 4 reciprocation extensions in X direction on the length direction of air intake supervisor 2-1
Conduit manifold 2-2, therefore, the air of inflow air intake supervisor 2-1 flows into after can uniformly branching to 4 main pipeline manifold 2-2
Air intake flow velocity is reduced to original 1/4 by sprue distributor box 3.Specifically, main pipeline manifold 2-2 is from air intake master
Pipe 2-1 starts to extend a distance into X direction first, then near reversed detour to air intake supervisor 2-1, it is unified vertically to
On each air intake of sprue distributor box 3 is connected to along Y-direction, rather than be directly passed through from horizontal X direction, this is to increase
Air distribution quality is advantageous between unit pipes, therefore after air can be via 4 main pipeline manifold 2-2 reductions of speed, from side-lower to uniform
Low speed inputs in sprue distributor box 3.
Left sides similar in sprue distributor box 3 and air intake are gradually to be tilted to the right from the bottom to top to contract
Inclined-plane, inclined degree are that the distance on lower left corner SOFC battery pipe unit 1 to 3 left side X-direction of distributor box is upper left corner SOFC
Battery pipe unit 1 is conducive to increase the air velocity close to top area to 2 times of distance between 3 left side of distributor box, thus
Reduce the static pressure in the region, finally make air along Y-direction evenly distribute after flow into battery-arrangements area.Sprue distributor box 3
Inner space can be divided into distribution area head 3-1, battery cell arrangement area 3-3 and distribution area tail portion 3-5 from left to right,
SOFC battery pipe unit 1 is distribution area head 3-1, SOFC cell tube array with left region to the left side of sprue distributor box 3
It is distribution area tail portion 3-5 that the region at place, which is battery cell arrangement area 3-3, SOFC cell tube with right region to right side, and from
The space of battery cell arrangement area 3-3 or more to 3 top surface of sprue distributor box is 3-4 at the top of distribution area.Air enters sprue
After distributor box 3, since distribution area head 3-1 has the diminishing feature in space from the bottom to top, therefore air can be carried out along Y-direction
Pressure regulation obtains the more uniform pressure distribution of Y-direction, and then air distributes input battery unit row with more uniform Y-Z plane
Arrange area 3-3.Under normal circumstances, on the one hand, since low air utilization ratio leads to high air mass flow, on the other hand, battery list
Identical permutation area 3-3 flow resistance with higher, most of air can be selected from battery cell arrangement area 3-3 or more, top
Runner bypass battery cell arrangement area 3-3, so as to cause between excessively poor battery unit air distribute quality.Therefore, this reality
The height that example distributes 3-4 at the top of area by narrowing, that is, the spacing of top layer SOFC battery pipe unit 1 and distributor top cover are applied,
1/3 is reduced compared to the spacing between SOFC battery pipe unit 1, increases the resistance that air passes through the fluid path, is forced more
Air flows through battery cell arrangements area 3-3, and excessive air is avoided to pass through distributor box 3 by way of increasing the path flow resistance
Upper edge around battery cell arrangement area 3-3 outflow, so that more air be forced to flow into battery cell arrangement area 3-3.Distribution
There is area tail portion 3-5 the resistance obviously to narrow to increase feature, between most right vertical setting of types SOFC battery pipe unit 1 and distributor right side
Away from reducing 1/3 compared to the spacing between SOFC battery pipe unit 1, by increasing tail portion collecting region 3-5 and battery cell arrangement
The flow resistance ratio of area 3-3 forces more air to flow through battery cell arrangement area 3-3, increases air between battery unit
Distribute quality.
8 offgas outlets are uniformly equipped on the right side of sprue distributor box 3, offgas outlet is divided into two column, and each column 4
Equidistant arranges along Y-direction, and the offgas outlet of top is not higher than height where top layer SOFC battery pipe unit 1.Such as Fig. 5 institute
Show, each offgas outlet is correspondingly connected with an exhaust collection manifold 4-1, and the exhaust collection manifold 4-1 of same column converges into a tail
The caliber of gas collecting main 4-2, exhaust collection supervisor 4-2 are gradually increased along tail gas discharge direction, therefore exhaust collection supervisor 4-2
Section from top to bottom gradually expands, and supervisor's sectional area, which is gradually increased, causes flow velocity in pipe to decline, according to Bernoulli Jacob's conservation of mechanical energy
Pressure increases in equation pipe, to realize uniform air trapping amount between exhaust collection manifold 4-1.Due to main pipeline manifold 2-
23 one sections of connection distributor boxes and exhaust collection manifold 4-1 are in orthogonal orientation, and air enters distributor box 3 and outflow point
Direction with case 3 is mutually perpendicular to, and promotes air to export diffusion upwards, to dextrad from entrance, the air of inflow can quickly enter electricity
Between battery cell arrangements area 3-3 each unit, while entrance and exit is evenly distributed on the axial direction of battery pipe unit, therefore
Air on each battery unit axial direction is uniformly abundant.
Then, as shown in fig. 6, two-way is imported directly by the exhaust collection supervisor 4-2 high hot exhaust gas collected positioned at mainstream
The inlet gas heating region 5-1 of 3 lower section of road distributor box, the region are made of heat exchanger housing 5-2, inlet gas heating zone
4 main pipeline manifold 2-2 are accommodated in the inner by domain, and manifold is extended in the area fully absorbs tail gas heat quantity for heated inlet
Air.
Finally, it designs, realizes under the premise of distribution outside air between battery unit and battery unit through the invention
Superficial air evenly distributes, to use exploitation high performance anode support type tubular type SOFC pile to lay a good foundation.
