MIXED PROTON-OXIDE ION-ELECTRON CONDUCTING CATHODE FOR SOFCS BASED ON OXIDE PROTON CONDUCTORS

摘要

The objective of this study is to develop compatible cathode for Ba(Zr_(0.1)Ce_(0.7)Y_(0.2)) O_(3-δ)(BZCY) based proton conducting SOFC. A new concept cathode is proposed for proton conductor, that is, proton-oxygen ion-election mixed conducting cathode. Introduction of proton conduction into conventional oxygen ion-electron conducting cathode greatly expand the reaction sites and thus decrease the interfacial resistance.
