Applied Electrochemistry and Metal Corrosion Protection


Fundamental aspects of the phase formation and morphology of films of the proton-conducting solid electrolyte La0.95Sr0.05ScO3–δ, produced by wet deposition from inorganic salts on a porous cathode substrate La0.6Sr0.4MnO3–δ. The conditions in which gas-tight films are deposited onto substrates with porosity of up to 25% were determined. The electrical conductivity of La0.95Sr0.05ScO3–δ films was examined in relation to temperature and gas-phase composition (рН2О, рО2). The effect of the architecture of the electrolyte membrane on its transport properties was analyzed. The results of the study are of fundamental importance for development of proton-ceramic fuel cells with a supporting electrode.
