摘要：
The results on optimizing the procedure of preparation of the electrode system within membrane-electrode assemblies (MEA) of solid-oxide fuel cells (SOFC) by joint sintering of electrodes at the enhanced temperature close to that of anode sintering are presented. The MEA are prepared based on membranes of the anionic conductor Hionic(TM) (Fuel Cell Materials, USA); the cathode is formed based on cation-deficient lanthanum-strontium manganite (La0.8Sr0.2)(0.95)MnO3 with addition of activated carbon for optimizing its microstructure; the anode is formed on the basis of cermet NiO/10Sc1CeSZ (89 mol % ZrO2, 10 mol % Sc2O3, 1 mol % CeO2). The results of electrochemical testing of model MEA are also shown.
