Double perovskite cathodes for proton-conducting ceramic fuel cells: are they triple mixed ionic electronic conductors?
(18)O and (2)H diffusion has been investigated at a temperature of 300 °C in the double perovskite material PrBaCo(2)O(5+δ) (PBCO) in flowing air containing 200 mbar of (2)H(2) (16)O. Secondary ion mass spectrometry (SIMS) depth profiling of exchanged ceramics has shown PBCO still retains significan...
