摘要:
Disclosed is an electrode having a novel configuration for improving performance of the electrode used in solid-oxide fuel cells, sensors and solid state devices, in which the electrode providing electron conductivity is coated with ion conductive ceramic ceria film, enabling an electron conductive path and an ion conductive path to be independently and continuously maintained, and additionally extending a triple phase boundary where electrode/electrolyte/gas are in contact, and a method for manufacturing the same. The electrode is manufactured by coating the prefabricated electrode for use in a SOFC or sensor with a porous oxygen ion conductive ceramic ceria film by a sol-gel method, whereby the electron conductive material and ion conductive material exist independently, having a new microstructure configuration with a greatly extended triple phase boundary, thus improving electrode performance. Accordingly, such electrode does not require high cost equipment or starting materials, owing to the sol-gel method by which low temperature processes are possible. Moreover, the electrode microstructure can be controlled in an easy manner, realizing economic benefits, and the electrode/electrolyte interfacial resistance and electrode resistance can be effectively decreased, thereby improving performance of electrodes used in SOFCs, sensors and solid state devices.
