The present work aims to predict the degradation in performance of a solid oxide fuel cell (SOFC) cathode owing cation interdiffusion between electrolyte and surface segregation. Cation migration (La0.60Sr0.40)0.95Co0.20Fe0.80O3-x (LSCF)-Gd0.10Ce0.90O1.95 (GDC) composite is evaluated relation time up 1000 h using scanning transmission electron microscopy (STEM)-energy-dispersive X-ray spectroscopy (EDXS). resulting insulating phase formed within GDC interlayer quantified by means volume...
980 nm VCSEL illumination eliminates the organic additives and densifies laminated multilayered SOFC NiO–YSZ|NiO–ScCeSZ|ScCeSZ|GDC|GDC scaffold in just 2.42 h compared to >100 needed for conventional thermal sintering process.
Electrolyte-Cathode interfaces are life-threatening regions of solid oxide fuel cells where degradation phenomena occur due to chemical interdiffusion. The Buffer layer is inserted between the electrolyte-cathode limit cation exchange across interface. However, state art buffer coated by screen printing does not fully prevent migration which results in formation insulating phases such as La 2 ZrO 7 and SrZrO 3 . Herein, a reliable four-layered (NiO-YSZ, NiO-CeScSZ, CeScSZ, GDC) thin...
This work reports development of large-area (12cm×12cm) planar anode-supported SOFC with 100cm2 active area by a tape casting, lamination and co-sintering method. The cell consists the nickel-8mol.% yttria-stabilized zirconia as support 0.7 mm thickness nickel-scandia stabilized (ScSZ) an anode functional layer. Processing optimization binder/plasticizer ratio casting slurry allowed to obtain green tapes good mechanical strength homogenous microstructure. Casting process parameter had also...
Solid oxide fuel cell (SOFC) technology has attracted great attention because of higher efficiency, flexibility, and eco-friendly stationary power generation system. However, its commercialization is hindered due to the lack durability high-cost. Herein, a facile exceptionally reliable 4-layered anode supported SOFCs with large area (12cm×12cm) was fabricated in single step co-firing process at 1400°C, which tape-casted green films NiO-YSZ, NiO-1CeScSZ, 1CeScSZ, GDC were laminated by...
