Novel Perovskite Structured Nd_0.5Ba_0.5Co_1/3Ni_1/3Mn_1/3O_3−δ as Highly Efficient Catalyst for Oxygen Electrode in Solid Oxide Electrochemical Cells

Semiconductor Heterostructure (SrFe0.3TiO3-ZnO) Electrolyte with High Proton Conductivity for Low-Temperature Ceramic Electrochemical Cells

“…The final peak of P 4 can be associated with adsorption, dissociation, oxygen diffusion, water formation, and evaporation of water vapor. Similar phenomena have been predicted in previous reports. ,, …”

“…A schematic of the reactions and proton transport involved in the water electrolysis cell is shown in Figure a. Further, the current density attained is higher than in the previously published reports. − Also, the electrolysis cell of composite heterostructure SFT-ZnO has delivered high current densities of 1.85, 1.5, 1.18, and 0.35 A cm –2 with different voltages of 2, 1.8, 1.6, and 1.3 V at 520 °C (see Figures b and e).…”

Highly Efficient and Stable Intermediate-Temperature Solid Oxide Fuel Cells Using PrCo0.5Ni0.5O3−δ Cathode

“…The electrochemical performance of cathodes is closely related to ORR and long-term durability. − As a mixed ion and electron conductor (MIEC) material, ABO 3 perovskite has attracted great attention to serve as cathode for SOFC due to its outstanding electronic conductivity and effective ionic conductivity. − Among them, cobalt-based perovskite oxide materials present superior catalytic performance. , However, its shortcomings are high coefficients of thermal expansion relative to typical electrolytes and relatively poor long-term stability, which limits the development of this material. , Up to now, ion doping, wet impregnation, and in situ exsolution methods to adjust the cell performance have been widely investigated. − Because the ion doping method is relatively simple and easy to duplicate, the oxygen vacancy concentration can be easily introduced by different A-site and B-site doping so as to obtain different electrochemical properties. , …”
