| dc.description.abstractEn | Solid state ionic devices based on high-temperature proton conductors can be used for various applications, especially in a new class of fuel cells, the Protonic Ceramic Fuel Cell (SOFC-H<sup>+</sup>). These systems are currently operating at intermediate temperatures (500–600 °C) and one of the major problems is the overpotential at the cathode side. In this context, various perovskite oxides AMO<sub>3 − <i>δ</i></sub> (A = La, Ba, Sr; M = Mn; Fe, Co, Ni) and A<sub>2</sub>MO<sub>4</sub>-type compounds (A = La, Nd, Pr or Sr; M = Ni) have been investigated. Their properties under moist cathodic atmosphere have been studied. Actually, they are stable and exhibit high electrical conductivity (<i>σ</i> > 100 S cm<sup>−1</sup>) as well as good electrocatalytic properties towards oxygen reduction. The electrochemical properties of these oxides deposited on the protonic electrolyte BaCe<sub>0.9</sub>Y<sub>0.1</sub>O<sub>3 − <i>δ</i></sub> have been studied and the Area Specific Resistances have been measured under air/H<sub>2</sub>O (3%) atmosphere. The obtained values at 600 °C, especially for Ba<sub>0.5</sub>Sr<sub>0.5</sub>Fe<sub>0.8</sub>Co<sub>0.2</sub>O<sub>3 − <i>δ</i></sub> and Pr<sub>2</sub>NiO<sub>4 + <i>δ</i></sub> show to be promising cathode materials for Protonic Ceramic Fuel Cell applications.</p> | |
