Electrochemical impact of the carbonate in ceria-carbonate composite for low temperature solid oxide fuel cell

Non-doped CeO2-carbonate nanocomposite electrolyte for low temperature solid oxide fuel cells

“…The promoted catalytic effect of alkali carbonate toward ORR may be credited [51]. Any, the ionic conductivity at the level of 10 -1 S cm -1 is still much higher than that of typical ceramic ionic conductivity.…”

A-site deficient semiconductor electrolyte Sr1−xCoxFeO3−δ for low-temperature (450–550 °C) solid oxide fuel cells

“…Also, the peak area has been modified by appropriate cobalt doping into the A-site of prepared perovskite Sr 0.7 Co 0.3 FeO 3 . 13,14,28,29…”

“…Also, the peak area has been modied by appropriate cobalt doping into the A-site of prepared perovskite Sr 0.7 Co 0.3 FeO 3 . 13,14,28,29 In contrast, cobalt doping enhances the area of the peak that got shrinks which claims that appropriate doping of cobalt might benet the structural changes and charges transfer in prepared Sr 1Àx Co x FeO 3 . The enhancement in the peak area is due to merging more defects in the lattice and enhancing the lattice parameter, leading to more active sites, which overall causes the ionic conduction-the peak located at 531.3 eV crossponds to the O-vacancies or surface oxide defects.…”

Realizing Coinstantaneous Multiple Benefits Generation from Sm0.075Nd0.075Ce0.85O2−δ/Al2O3 Heterostructure Electrolyte by Interfacial Engineering

“…Solid oxide fuel cell (SOFC) has been regarded as an efficient and promising energy conversion device featuring fuel flexibility, high efficiency, and low emissions. − The traditional SOFCs are based on Y 2 O 3 stabilized ZrO 2 (YSZ) electrolyte material and typically operate at high temperatures (above 800 °C) resulting in several limitations, such as material incompatibility, long start-up time, high operation costs, difficult sealing, and poor operational stability. − The semiconductor ionic SOFCs can address these issues due to their unique characteristics, like lower operating temperatures (400–550 °C) and employing a wide range of electrolyte materials, including perovskites, fluorites, insulators, and semiconductor heterostructure materials. ,, In recent decades, efforts have been focused on semiconductor heterostructure electrolyte materials to mitigate those issues and facilitate the commercialization of low-temperature SOFCs (LT-SOFCs).…”
