Description
Technical field
The invention belongs to high temperature field of solid oxide fuel, particularly to one kind uses plasma spray
Apply the Cu-Mn-Co spinelles/metal connector composite with pyroconductivity and high-temperature oxidation resistance prepared, application
Metallic interconnection materials are used as in SOFC.
Background technology
SOFC (Solid oxide fuel cell, SOFC) is a kind of chemical energy by fuel
The electrochemical appliance of electric energy is converted directly into by electrode reaction.Due to no burning and mechanical process, SOFC chemistry-electric energy
Amount conversion efficiency is up to 85%, while the features such as having pollution-free and noiseless.In general, SOFC operating temperature is 800
DEG C~1000 DEG C, high operating temperature means that fuel can be reformed in fuel battery inside and avoid outside reformation, and
The high-quality byproduct produced is that heat energy can be used for cogeneration of heat and power；While different types of hydrocarbon fuels, such as oxygen, first
Institute, natural gas etc. can be used for cogeneration of heat and power.Another advantage that high operating temperature is brought is to substantially improve kinetics,
So that SOFC no longer needs metallic catalyst.With the development of middle low temperature SOFC technologies, the reduction of battery operating temperature to adopt
Prepared metal connector with high temperature resistant, Antioxidant alloy material and be possibly realized.With ceramic material LaCrO3Compare, metal alloy tool
There are good air-tightness, electrical conductivity and thermal conductivity height, bipolar plates uniformity of temperature profile, high mechanical strength and cost easy to process low aobvious
Write advantage.High-temperature oxidation resistant alloy is considered as that can be applied to one of most promising metallic interconnection materials of middle low temperature SOFC at present,
But, easily poison cell cathode etc. urgently there is also the Cr for mismatching and volatilizing with YSZ electrolyte thermal coefficient of expansion
The problem of solution.
In recent years, the coating material that can be applied to SOFC metal connectors barrier layer is widely studied, current coating material
Material is broadly divided into following four classes material：Active element oxide, RE perovskite oxide, spinel oxide and MAlCrYO
High-temperature resistant alloy material.Active element oxide refers mainly to the oxide of the elements such as Y, La, Ce, Hf, and this type oxide can have
Effect ground improves oxide layer and metallic matrix adhesion, reduces the thickness of oxide layer, it is possible to be effectively reduced the height of alloy substrate
Warm oxidation rate, main cause is that the affinity of Y, La, Ce, Hf isoreactivity element and oxygen is stronger, and they can be to oxygen activity highest
Superficial layer migration and in the grain boundaries segregation (active element ionic radius is relatively large) of oxide layer, so as to prevent other ions
(such as Cr) to external migration and reduction interface Lacking oxygen number.Elisabetta Tondo etc. are existed by galvanoplastic
AISI430 stainless steel surfaces prepare Y2O3、Y2O3/Au、Y2O3/Co3O4Deng composite coating, Y is found2O3It can be volatilized with matrix
The chromium gone out forms the perovskite structure oxide of conduction, and this layer of oxide can be effectively reduced the oxidation rate of matrix, reduces
Contact resistance, eliminates the cracking of oxide skin(coating).Perovskite structure oxide (ABO3) can be by adulterating (Sr, Fe, Cu etc.) at B
Adjust its electronic conductivity and thermal coefficient of expansion.Not only electrical conductivity is higher but also can be following point for RE perovskite type coating
Spar oxide skin(coating) provides active element (such as La, Mn), improves the oxidation behavior on barrier layer.Because perofskite type oxide
Belong to oxygen ion conductor and prepares coating is not fine and close enough, it is impossible to effectively stop Cr past external diffusion and the inside diffusion of oxygen.
Spinel oxides (AB2O4) coating has good electric conductivity, while the thermal expansion system with battery miscellaneous part
Count also comparison match.Above all spinelle coating is fine and close and with good absorption Cr ability, therefore is metal alloy
The quality material of surface barrier.(Mn,Co)3O4、(Cu,Mn)3O4、(Cu,Fe)3O4And Co3O4Deng spinel strucutre oxides
Calorifics and electric property are excellent, with the thermal coefficient of expansion close with metal alloy, therefore are suitable for being applied to metal connector
Coating for surface protection.
The content of the invention
Negative electrode is easily caused under solid oxidized fuel working environment in order to solve metal connector to poison and resistance to high temperature oxidation
It is the problem of scarce capacity, multiple with spinelle/metal connector it is an object of the invention to provide a kind of SOFC
Condensation material, with pyroconductivity and high-temperature oxidation resistance
Another object of the present invention is to provide a kind of SOFC spinelle/metal connector composite wood

Oxidation generation Cr2O3Thermally grown layer, can suppress the external diffusion of Cr elements and the interior diffusion of O elements.
Addition element Cu can dramatically increase (Mn, Co) 3O4 spinelles stability and electric conductivity.The electric conductivity of spinelle by
Transition is produced between Mn3+ and Mn4+ of the electronics on octahedral site, and the size of electrical conductivity depends on Mn3+ and Mn4+ on B positions
Concentration and ratio.Cu doping, the cation on A or B positions is may replace according to addition concentration, and B have priority.Due to Cu
+ can exist simultaneously with Cu2+ ions, different valence state cation is conducive to increasing conductance in octahedral site, and improves composite wood
Expect performance, this has good application value.
