Mixed-conducting cathode materials for protonic ceramic fuel cells: Proton uptake and defect interactions

Conference Dates

March 10-14, 2019


A cathode in a proton-conducting ceramic fuel cell (PCFC) should meet several criteria including high catalytic activity, electronic conductivity, sufficient proton conductivity, phase stability, etc. to achieve good performance. The proton conductivity allows the oxygen reduction reaction to extend from the triple phase boundary to the whole surface of the cathode (so-called "bulk path").
