(La1-xPrx)2Mo2O9 powders were synthesized by solid state reaction for x = 0.00, 0.10, 0.25, 0.50, 0.75 and 1.00. Dense pellets were obtained by conventional sintering in air. Their thermal stability and thermal conductivity were measured from 100 to

International audience; La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) electrode deposited on Gadolinium Doped Ceria (GDC) has been characterized by cyclic voltammetry and impedance spectroscopy in the temperature range of 300 to 700 °C. We demonstrate that the L
