Disproportionation

Journal of Materials Chemistry A

Cubic La0.7Sr0.3Mn1−xNi<italic>y</italic>O3−δ undergoes the hydration reaction with the charge disproportionation between Mn and O atoms, and thus, can reduce the interfacial polarization of protonic solid oxide cells due to the H+/O2−/e− triple conductivity.
