Studies on solid electrolyte gas cells with high-temperature-type proton conductor and oxide ion conductor

Various types of gas cells are studied using high-temperature-type proton and oxide ion conductors as the solid electrolyte. Steam and hydrogen concentration cells could be constructed using the SrCeO₃-based proton conductive solid electrolyte. Using the oxide ion conductor, YSZ, the steam concentration cell could also be constructed in hydrogen atmosphere. Some characteristics of these cells are discussed.
