摘要：

Proton conduction in SrZrO3-based oxides which were doped with aliovalent cations such as Yb3+, Y3+, Ga3+, Al3+ and In3+ was investigated. These ceramics showed proton and hole mixed conduction in water vapor containing atmosphere at relatively high oxygen partial pressure at high temperature. Hydrogen concentration cell using these oxides as a solid electrolyte could be constructed and showed stable EMF close to theoretical value calculated from Nernst's equation. Electrochemical hydrogen permeation could be carried out at high temperature using these oxides as a solid electrolyte. Hydrogen evolution rate was close to the value calculated from Faraday's law.
