Effects of yttrium doping on oxygen conductivity in Ba(Fe, Co, Zr, Y)O 3− δ cathode materials for proton ceramic fuel cells
Chiyoung Kim, Ryan Jacobs, Jack H. Duffy, Kyle S. Brinkman, Harry W. Abernathy, Dane MorganAIMD simulations show that Y doping reduces oxygen conductivity in BCFZY PCFC cathodes through increased oxygen migration barriers. Grain boundary transport is proposed as the dominant limitation in experimental oxygen transport.
