Abstract
This study investigates the effect of water vapor and hydrogen on the conductivity of perovksite-like cuprates Y(Pr)Ba2Cu3Oy and Sr2CuO3 at t = 20–150°С. It is demonstrated that the interaction of cuprates with a hydrogen-containing atmosphere results in intercalation of hydrogen or water into the structure of compounds and produces ionic current carriers. Measurements of the emf of cuprate-based electrochemical cells reveal that such cells, where cuprates act as proton-conductive membranes, have the capacity to generate emf.
