Nanostructured air electrodes play a crucial role in improving the electrocatalytic activity of oxygen reduction and evolution reactions solid oxide cells (SOCs). Herein, we report fabrication nanostructured BaCoO3-decorated cation-deficient PrBa0.8Ca0.2Co2O5+δ (PBCC) electrode via combined modification direct assembly approach. The approach endows dual-phase with large surface area abundant vacancies. An intimate electrode-electrolyte interface is situ constructed formation catalytically...
Nanofibers have great promise as a highly active air electrode for reversible solid oxide cells (ReSOCs); however, one thorny issue is how to adhesively stick nanofibers electrolyte with no damage the original morphology. Herein, PrBa0.8Ca0.2Co2O5+δ (PBCC) are applied an by facile direct assembly approach that leads retention of most unique microstructure nanofibers, and firm adhesion nanofiber onto achieved applying electrochemical polarization. A single cell PBCC exhibits excellent maximum...
Nanostructured anodes generate massive reaction sites to oxidize fuels in solid oxide fuel cells (SOFCs); however, the nonexistence of a practically viable approach for construction nanostructures and retention these under harsh operating conditions SOFCs poses significant challenge. Herein, simple procedure is reported nanostructured Ni-Gd-doped CeO2 anode based on direct assembly pre-formed nanocomposite powder with strong metal-oxide interaction. The directly assembled forms...
Modulation of the surface chemistry air electrodes makes it possible to significantly improve electrocatalytic performance solid oxide cells (SOCs). Here, BaGd
Solid oxide fuel cells (SOFCs) are considered one of the most efficient energy conversion technologies. One distinct advantages SOFCs is that in addition to pure hydrogen, hydrogen-rich fuels such as hydrocarbons, hydronitrogens, and biomass can be fed generate electrical energy. However, state-of-the-art nickel-based cermet anodes suffer from carbon deposition or nitridation fuels. To solve these problems, thermocatalysts widely applied fueled SOFCs. The integration plays a critical role...
Bilayer Bi0.85-xPr0.15RExFe0.97Mn0.03O3/CuFe2O4 (BPRExFMO/CuFO, RE = Sr, Dy) thin films were prepared on FTO/glass substrates by the chemical solution deposition method. The structure transition does not appear after ion doping, which is confirmed XRD and its refined results. samples remain in trigonal R3c:H BFO phase tetragonal I41/amd CuFO phase. asymmetric character of leakage current density curves resistive switching effects have been explored. And substitution impacts may be due to...
Ruddlesden–Popper oxide La2NiO4+δ (LNO) has a high ionic conductivity and good thermal match with the electrolyte of solid fuel cells (SOFCs); however, LNO suffers from performance decay owing to La surface segregation under operation conditions SOFCs. Herein, we report an in situ electrochemical decoration strategy improve electrocatalytic activity durability cathodes. We show that polarization leads construction LNO@Pt core–shell structure, significantly suppressing detrimental effect on...
Development of fuel electrodes for reversible solid oxide cells (RSOCs) is important achieving good performance and stability under both cell electrolysis operation modes. In this work, CeO2-decorated La0.43Ca0.37Ti0.94Ni0.06O3−δ (denoted as LCTN-Ce) were prepared via a simple hydrothermal route, where CeO2 uniformly decorated onto the external surface LCTN-Ce electrode with in situ exsolved Ni nanoparticles (NPs) after reduction treatment. The content can be regulated by adjusting treatment...
