“…Nevertheless, synthesis temperatures of 1125°C [35] and 1000°C [36] have been mentioned, which are significantly higher than 900°C. Finally, for LSCM, heat-treatment temperatures of 1300°C, [28] 1200°C, [29] 1100°C [30] or 800°C [31] are reported for the preparation of a pure phase; most of them are still higher than 900°C.…”

An alternative route to acrylamide gel polymerisation is presented for the preparation of oxide nanopowders. Within this method, cations first dissolved in an aqueous solution are subsequently trapped inside a 3D chelating gel before fast-drying, which leads to a stable precursor. Thermogravimetry and differential thermal analysis studies have been performed to determine the best calcination conditions. After calcination, the resulting powders have been characterised by X-ray diffraction, FEG-scanning electron

“…At 850 ° C, LSCM-Cu-Pt anode gave P max of 0.85 and 0.52 W cm − 2 in dry H 2 and dry CH 4 , respectively. [ 276 ] It was stated that Pd promoted the exchange and diffusion of oxygen species and the CH 4 decomposition. [ 277 , 278 ] Co-impregnation of Cu as the electronic current collector and Pd as the electrocatalyst into porous LSCM anode layer improved the single cell performance to 0.89 and 0.6 W cm − 2 in dry H 2 and dry CH 4 , respectively.…”

Solid oxide fuel cells (SOFC) are highly efficient energy conversion devices with the advantage of directly utilizing hydrocarbon fuels. Starting with a short introduction about the fuel challenges and early achievements in this field, this review paper focuses on advances in oxygen‐ion conducting electrolyte‐based SOFC during the last 15 years. Robust anodes immune to carbon deposition are a prerequisite for direct hydrocarbon SOFC. In this paper, direct hydrocarbon SOFC anode materials are classified into three general categories: Ni‐cermet, Cu‐cermet, and oxide‐based anodes. Oxide anodes are further classified in terms of their crystalline structures, namely fluorite, rutile, tungsten bronze, pyrochlore, perovskite, and double perovskite. Achievements and recent advances on these SOFC anodes are reviewed and discussed. The concluding remarks summarize the pros and cons of direct hydrocarbon SOFC anode materials along with the perspective of future research trends.

Sol-Gel Processing for Conventional and Alternative Energy

View full text Add to dashboard Cite

Solid oxide fuel cells (SOFCs) have potential to be the most efficient and cost-effective system for direct conversion of a wide variety of fuels to electricity. The performance and durability of SOFCs depend strongly on the microstructure and morphology of cell components. As a unique synthesis and processing technique with easy control of composition, structure, morphology, and microstructure, sol-gel processes have been widely used for fabrication of key SOFC materials or critical components with desired properties or functionalities unattainable otherwise. In this chapter, we provide an overview on sol-gel processes applied for preparation of homogeneous and fine powders of electrolyte, electrode, and ceramic interconnect materials, for deposition of dense electrolyte membranes or porous electrode films, and for modification of electrode or metallic interconnect surface or interface to enhance catalytic activity, to improve tolerance to coking or contaminant poisoning, and to increase stability against oxidation, reduction, or other degradation mechanisms. While significant progress has been made in controlling and tailoring the composition, microstructure, morphology, and hence functionality of materials and components, many challenges still remain to make sol-gel processes cost-effective and versatile for many applications. The development of novel sol-gel processes as well as the exploration of the existing ones to new applications continues to be an intriguing research pursuit.
