Acceptor doping effects on microstructure, thermal and electrical properties of proton-conducting BaCe0.5Zr0.3Ln0.2O3-δ (Ln = Yb, Gd, Sm, Nd, la or Y) ceramics for solid oxide fuel cell applications
(2016)In the present work, six materials belonging to Ln-doped BaCeO3-BaZrO3 system (Ln = Yb, Y, Gd, Sm, Nd, La) are prepared and characterized. The impact of the type of the acceptor dopant on i) the microstructure (relative ... -
The effect of cobalt oxide addition on the properties of gadolinium doped barium cerate
(2009)In the present work the effect of cobalt oxide addition on the density and on the electrical properties of gadolinium doped barium cerate is investigated. A series of BaCe0.9-xGd0.1CoxO3-δ (?=0.00, 0.01, 0.03, 0.05, 0.07, ... -
An electrochemical method for the determination of concentration and diffusion coefficient of ammonia‑nitrogen gas mixtures
(2018)In the present investigation an electrochemical method for the determination of concentration and diffusion coefficient of ammonia in nitrogen (NH3/N2) is proposed by the means of a solid-state amperometric sensor based ... -
