N2 - Transient phenomena of electrochemical hydrogen pumps, permeation of hydrogen on passing a direct current through a proton-conducting electrolyte, were investigated. Variations of proton transport in electrochemical hydrogen permeation by changing the anode gas were investigated potentiostatically at 900 °C using a SrCe0.95Yb0.05O3-α proton-conducting solid electrolyte. Changes in direct current and charge carriers were examined on changing the anode gas from Ar to H2 and back while keeping Ar as the cathode gas. In another variation of the anode gas with the two hydrogen isotopes, H2 and D2, the time dependence of the evolution of hydrogen isotope species at the cathode was analyzed to estimate the mobilities of protons and deuterons in the electrolyte.
