Ni-SDC cermet anode fabricated from NiO–SDC composite powder for intermediate temperature SOFC

Fabrication and performance of gadolinia-doped ceria-based intermediate-temperature solid oxide fuel cells

“…Currently, various processes have been developed for the preparation of thin electrolytes on porous electrode substrates, such as screen printing [12], dry pressing [13,14], spray coating [15], slurry spin coating [16], magnetron sputtering [17], and tape casting [11,18]. For instance, Doshi et al [11] applied a multi-layer tape casting technique to fabricate a fuel cell that consisted of a 30-m thick Gd 0.2 Ce 0.8 O 1.9 (GDC) electrolyte, a Ni-GDC anode and an ANLC-1 cathode.…”

Tailoring gadolinium-doped ceria-based solid oxide fuel cells to achieve 2 W cm−2 at 550 °C

“…Despite the numerous studies on each part (anode, cathode and electrolyte), high-performance LT-SOFCs, especially ceriabased LT-SOFCs [35][36][37][38] , have been rarely reported with few exceptions: Wachsman et al 4 39 and Choi et al 40 and Park et al 41 recently reported over 1.2 W cm À 2 at 550°C in a cell with a PrBa 0.5 Sr 0.5 Co 1.5 Fe 0.5 O 5 þ d (PBSCF05) cathode. Here, we report an original cell design, the core/shell-fibre-structured BSCF-GDC cathode | thin GDC electrolyte | nanocomposite Ni-GDC AFL | Ni-GDC anode fuel cell to achieve high and stable performance GDC-based LT-SOFCs.…”

Enhanced electrochemical activity and long-term stability of Ni–YSZ anode derived from NiO–YSZ interdispersed composite particles

“…The apparatus used to make the IC particles was a high speed attrition type one. [10][11][12][13] The apparatus was consisted of the stainless steel chamber and the rotor, and it employed no media ball. The clearance between the rotor and the inside wall of the chamber was fixed at 1 mm.…”

“…7,8 Prefabrication of the composite particles followed by the electrode fabrication using conventional ceramic processing is a promising way to control the microstructure of composite electrodes. [9][10][11][12][13][14][15][16] Recently, we successfully fabricated coated composite (CC) particles consisted of large core-particle coated by nanoparticles using a mechanochemical processing under dry ambient. [10][11][12] The composite particles provided well organized electrode microstructure and resulted good electrochemical performance.…”
