Description
Technical field
The invention belongs to field of batteries, more particularly, to one outflow chamber SOFC pile.
Background technology
SOFC (SOFC) is a kind of generating that the chemical energy of hydrocarbon fuel is converted into electric energy
Device, has energy conversion efficiency advantage high, free of contamination.At present, the SOFC structure of main flow has tubular type and flat two kinds of knots
Structure.Planar SOFC has manufacture and assembles simple, low cost and power density advantages of higher, is increasingly becoming Jiao of research both at home and abroad
Point.Classifying according to supporter, planar SOFC is divided into again electrolyte-supported, cathode support and anode support structure.Electrolyte props up
Support SOFC uses thicker ceramic oxygen ion conductor material to carry out structure support, and overall ohmage is bigger, it is necessary to 1000
Hot operation about DEG C.In this case, the LaCoO using doping more3Pottery is as metallic interconnection materials, and its cost is very
Costliness, generating efficiency is low, is unfavorable for the commercialization of SOFC.The SOFC of cathode support use perovskite ceramic material support,
, easily there is concentration polarization, is also unfavorable for the popularization of SOFC in its poorly conductive.The SOFC of anode-supported is by the Ni/YSZ of high conductivity
Ceramic metal is as support body material, and anode functional layer, electrolyte, negative electrode are by silk screen printing, electrochemical deposition or chemistry gas
The technique such as deposition is sequentially prepared on supporter mutually, the design reduces the concentration polarization of battery, reduces ohm electricity of battery
Resistance, ultra-thin electrolyte design makes SOFC operating temperature be reduced to less than 800 DEG C, metal connector being applied in pile
For possible
What planar SOFC was more conventional has interior stream chamber and the electric pile structure design of two kinds of outflow chamber.Air-flow in the pile of interior stream chamber
Chamber is formed by connector and encapsulant stacking successively, and gas transmission in air flow chamber is oriented parallel to pile stacking direction,
Vertical with airflow direction in battery layers, owing to air flow chamber and bipolar plates are an entirety, therefore bipolar plate structure is complex, difficult processing
Degree is big, and with high costs.In exterior air drain pile, air flow chamber separates with reactor core as gas buffer room, simplifies to a certain extent
The structure of bipolar plates.In above two structure, if bipolar plates uses integrated molding, it is contemplated that the heat change in the course of processing
Shape, it is necessary to use thicker steel plate just can obtain desired structure, this can be greatly increased pile volume, reduce volume energy density.
More easy way is that gripper shoe and gas distributor are processed recombinant respectively, can simplify the preparation work of gas distribution plate
Skill, has also derived the gas distribution plate of various form, includes straight channel, serpentine flow path, branch shape runner, gas flowfield plate shape
Runner etc..
In planar SOFC, connector bipolar plates is made up of gripper shoe and gas distribution plate, and gas distribution plate has concurrently and uniformly divides
Gas distribution and the function collecting battery surface electric current.In general pile, bipolar plate structure is two classes, and a class two-side current collecting device is all adopted
Designing with metal channels, the bipolar plates processing technique of this design is complicated, relatively costly.One class bipolar plate design cathode collector is adopted
Design with metal channels, and anode current collector is frequently with foam Ni or Ni felt, the drawback of this design, nickel foam and metal channels
Different at the deformational behavior of high temperature stress, nickel foam at high temperature intensity is the lowest, and bipolar plates both sides are really asymmetric answering
Power is transmitted, and when pressure transmits from top to bottom, it is possible that the uneven distribution of stress, has influence on the sealing of battery and connects
Touch.Additionally, knowable to the microstructure of nickel foam, its effective area contacted with galvanic anode is the least, electric current collection is imitated
Rate also has the space improved further.
