Description
Technical field
The present invention relates to SOFC technical field, the system of a kind of anode of solid oxide fuel cell
Preparation Method.
Background technology
SOFC (SOFC) be a kind of can directly the chemical energy of fuel be efficiently converted to electric energy send out
Electric installation, has that efficiency is high, it is low to pollute and the fuel source advantage such as extensively.The key component of monomer SOFC includes electricity
Xie Zhi, negative electrode, anode etc..The Main Function that electrolyte plays is to conduct ion and isolation reacting gas between electrode；Negative electrode
Effect be to promote the dissociating and spread of oxidizing gas；The oxidation of fuel gas can be played catalytic action by anode.At present
Most having the SOFC of application prospect is anode-supported cells.In anode support type SOFC, anode except as supporter,
Or the catalyst of fueled electrochemical oxidation reaction, and provide reaction interface.
The material that may be used for SOFC anode includes the noble metals such as Pt, Au, Ag, and some are stable in reducing atmosphere
Electronic conductance pottery and mixing conductance pottery, such as the oxides such as ZrO2, CeO2 and the oxide of doping.Noble metal is at height
Under temperature readily volatilized, and cost is the highest, is therefore not suitable for long-term work and popularization.And doping oxide electrode is the most also located

Ni/YSZ cermet anode.This anode can guarantee that higher catalytic, porous, chemical compatibility, thermally matched
Property, high conductivity etc..Ni/YSZ cermet anode can be prepared by multiple method, as pottery forming technique includes
Flow casting molding and rolling formation, coating technology includes silk screen printing and mud coating etc., and deposition technique commonly uses plasma spray coating
With chemical gaseous phase deposition etc..These methods need the testing equipment of costliness mostly, and need the highest sintering condition, these
All it is unfavorable for that the commercialization of anode is promoted.And Ni/YSZ cermet anode is when directly utilizing hydrocarbon fuel, easily sends out
Raw serious carbon deposition phenomenon.The seminar of Gorte uses the most inert Cu to replace Ni in YSZ matrix, improves electricity
The anti-carbon performance of pole.But owing to the fusing point of Cu and oxide thereof is relatively low, it is impossible to sinter with after traditional curtain coating, dry-pressing
Prepare etc. technique.This seminar uses the industrial conventional infusion process of catalysis.Afterwards, a lot of seminars use infusion process
In preparing various SOFC anode, and achieve significant achievement.
At present, utilize SOFC anode prepared by infusion process, the restraining factors that stability is the most maximum.This is due to dipping
Time, in anode, the catalyst component primary attachment of dipping is on the top layer of anode support, often blocks the hole on surface, makes
Obtain impregnation liquid can not continue deeper into inside supporter.It is the most uneven that this causes catalyst to be distributed in supporter, at 700 DEG C
Can occur under above operating temperature to migrate and sintering, stability declines the most therewith.Simultaneously as catalyst can not fully arrive
Reaching anode and electrolyte interface to be catalyzed the electrochemical oxidation of fuel, this will cause the increase of battery impedance, reduce output
Performance.
