Hydrostatic pressure decreases the proton mobility in the hydrated BaZr0. 9Y0. 1O3 proton conductor
Q Chen, A Braun, A Ovalle, CD Savaniu… - Applied Physics …, 2010 - pubs.aip.org
Impedance spectroscopy on the hydrated proton conductor BaZr0. 9Y0. 1O3 at high
temperatures shows that the bulk proton conductivity activation energy Eb scales with the
strain parameter, as achieved by hydrostatic pressures up to 2 GPa, suggesting that large
lattices favor proton diffusivity. At high temperature, Eb increases upon pressure by 40%.
The grain boundary activation energy Eg is around twice as Eb, indicating higher proton
mobility in grain boundaries as a result of pressure induced sintering. An expanded lattice …
