Cubic La<sub>0.7</sub>Sr<sub>0.3</sub>Mn<sub>1−x</sub>Ni<italic>y</italic>O<sub>3−δ</sub> 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<sup>+</sup>/O<sup>2−</sup>/e<sup>−</sup> triple conductivity.
