Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): PROTON CONDUCTING OXIDES -- THERMOELECTRIC POWER Аннотация: A theory of thermopower for proton conducting oxides (PCO) with protons, oxide ions and different electron charge carriers has been developed. The thermopower альфа of SrCe0.95Y0.05O3 дельта, BaCe0.9Nd0.1O3 дельта and of a zirconium–yttrium electrolyte as a reference material was measured in both oxidizing and reducing atmospheres. The analysis of the data obtained for the region of pure protonic conduction of SrCe0.95Y0.05O3 дельта using our theoretical results and including vibrational and configurational contributions to альфа allowed determining both the partial entropy of protons and their heat of transport. The concentrations of protons and their temperature dependences determined from the entropy term agreed well with the experimental data available from hydrogen uptake studies. \\\\Cserver\\dist\\НБО\\Cтатьи БД ИВТЭ\\Solid State Ionics\\2003, V. 162-163, С. 55-61.pdf |
