He had rallied from critical illnesses before, but this time it seemed that the end had come. I boarded a plane for London. The muffled roar of the all-but-...
متن کاملDouble perovskite cathodes for proton-conducting ceramic fuel cells: are they triple mixed ionic electronic conductors?
18O and 2H diffusion has been investigated at a temperature of 300 °C in the double perovskite material PrBaCo2O5+δ (PBCO) in flowing air containing 200 mbar of 2H216O. Secondary ion mass spectrometry (SIMS) depth profiling of exchanged ceramics has shown PBCO still retains significant oxygen diffusivity (~1.3 × 10-11 cm2s-1) at this temperature and that the presence of water (2H216O), gives ri...
