The electrochemical influence and oxygen exchange properties of mixed conducting electrode materials on solid oxide electrolytes

摘要

Electrolyte electrode materials combinations of Er2O3 stabilized Bi2O3 and mixed i.e. both electronic and ionic conducting materials are investigated in order to lower electrode polarization losses and operating temperatures of electrochemical sensors, pumps and SOFC reactors made of them. 18O exchange rates are correlated with exchange current densities.
