Insights on thermal and transport features of BaCe0.8-xZrxY0.2O3-delta proton-conducting materials
(2015)
BaCe0.8-xZrxY0.2O3-delta-based materials (BCZYx, 0 <= x <= 0.8) are obtained through a modified citrate-nitrate combustion method at 1150 degrees C with following sintering at 1450 degrees C. Then their thermomechanical ...
Sulfur and carbon tolerance of BaCeO3-BaZrO3 proton-conducting materials
(2015)
In the present work, BaCe0.8-xZrxY0.2O3-delta-based ceramic samples (BCZYx) are prepared and their chemical stability in corrosive atmospheres containing high concentrations of H2O, CO2 and H2S is investigated. Based on ...
Exergetic potential of fuels: The case of a SOFC-based power plant
(2004)
The method of exergy analysis is presented for a SOFC power plant involving external steam reforming and fed by methane and ethanol. The optimal operation parameters of the integrated SOFC plant are specified after minimizing ...
Novel composite solid state electrolytes on the base of BaCeO3 and CeO2 for intermediate temperature electrochemical devices
(2013)
In the present work, nano-sized powders of (1-x)Ce0.8Sm0.2O2-delta-xBaCe(0.8)Sm(0.2)O(3-delta) (x = 0, 0.3, 0.5, 0.7 and 1) were obtained by solution combustion synthesis (self-combustion synthesis, SCS) method of nitrate ...
