Solid oxide fuel cell (Solid Oxide Fuel Cell, SOFC) generation technology is to solve high efficiency of energy
Using one of the approach with the difficult problem of environmental protection, chemical energy directly can be converted to electric energy and thermal energy by electrochemical reaction by SOFC, tool
There are pollution-free, high efficiency, high fuel tolerance.But cheap fuel is in use, chemistry occurs for anode and sulfur-containing impurities instead
This sulfur poisoning phenomenon that sulfur poisoning product (absorption sulphur simple substance, metal sulfide etc.) should be generated is to restrict the commercialized master of SOFC
One of reason is wanted, is to need key problems-solving in SOFC commercialization process.Currently, researcher is by finding substituted type anode
Material, Humidified fuel, promotes the methods of operating temperature to inhibit anode sulfur poisoning at installation desulfurizer, but metal anode material

It is solution that the regeneration method of anodic composition, structure and chemical property can utmostly be restored by, which finding after the failure of anode sulfur poisoning,
The certainly key point of anode sulfur poisoning problem.
In pure H2In fuel, under larger discharge current density, for a long time (hour tens of or up to a hundred) it is multiple to sulfur poisoning Ni base
Heyang pole (Ni/YSZ, Ni/GDC) carries out constant-current discharge can restore its chemical property, the recovery of chemical property to a certain degree
The O that anode is transported to by cathode is generated in the process2-, a large amount of O2-It can be with fuel H2Redox reaction, O occurs2-It can't participate in
Removing sulfur poisoning product, and H2It may be that sulfur poisoning anode performance realizes that part is extensive that redox reaction, which occurs, with sulfur poisoning product
The main reason for multiple, but this process is extremely slow, even hour up to a hundred can not restore the electrification of sulfur poisoning anode completely
Performance is learned, and in expensive, explosive H2In by long-time constant-current discharge make anode obtain regeneration method be SOFC business
It is unacceptable to change institute, and developing time-consuming short, high-efficient anode regeneration method is a good problem to study.Whether can shield
