Mixed ionic-electronic conducting materials are not used as a single-layer electrolyte of solid oxide fuel cells (SOFCs) at relatively high operating temperatures ~800 °C. This is because significant decrease in the open-circuit voltage (OCV) and, consequently, SOFC power density. The paper presents comparative analysis anode-supported properties obtained within temperature range 600 to 800 °C with yttria-stabilized zirconia (YSZ) and gadolinium-doped ceria (GDC) thin films. Electrolyte...
Samarium-doped ceria (SDC) is considered as an alternative electrolyte material for intermediate-temperature solid oxide fuel cells (IT-SOFCs) because its conductivity higher than that of commonly used yttria-stabilized zirconia (YSZ). The paper compares the properties anode-supported SOFCs with magnetron sputtered single-layer SDC and multilayer SDC/YSZ/SDC thin-film electrolyte, YSZ blocking layer 0.5, 1, 1.5 μm thick. thickness upper lower layers are constant amount to 3 1 μm,...
Abstract The multilayer La 0.6 Sr 0.4 CoO 3 /Ce 0.9 Gd 0.1 O 2 /La (LSC/CGO/LSC) thin film cathode of the solid oxide fuel cell (SOFC) with different thickness LSC and CGO layers are obtained by magnetron sputtering. Cathodes deposited onto NiO/8YSZ anode‐supported 8YSZ/CGO bilayer electrolyte. influence on SOFC performance is investigated in temperature range between 800 600°C. It shown that thin‐film allows increasing efficiency, optimum provides maximum power density for SOFCs. 2430,...
Abstract The possibility of fabricating large‐area solid oxide fuel cells (SOFC) with thin film electrolyte using a commercial physical vapor deposition technology is investigated. Yttria‐stabilized zirconia (YSZ)/gadolinium‐doped ceria (GDC) bilayer successfully deposited on 10 × 5 cm 2 NiO/YSZ anode support by reactive magnetron sputtering. microstructure the was studied scanning electron microscopy. Current‐voltage characteristics at temperature 750°C and their power stability under...
A planar solid oxide fuel cell (SOFC) was fabricated using a commercial Ni/yttria-stabilized zirconia (YSZ) anode support, an YSZ/gadolinium-doped ceria (GDC) thin-film electrolyte, and composite cathode of La0.6Sr0.4Co0.2Fe0.8O3/Gd0.1Ce0.9O1.95 (LSCF/GDC). small, three-cell, SOFC stack is assembled 10 cm × single cells, metallic interconnects, glass-based sealing. The performance examined at various flow rates H2 + N2 air fixed temperature 750 °C. three-cell with crossflow design produced...
Within Japan, the atomic bombing of Hiroshima is understood as a national experience that sets country apart from nations have been spared such devastation. A special phrase Japanese use to describe their yuitsu hibaku kokka, ‘the only has experienced bombing’. This become powerful cliché for depicting Japan and international audience. Even though was comparatively small group before it spread larger collectivity, its transformation into collective regarded natural outcome, explained by...
Thin-film electrolyte made of 8-mol% yttria stabilized zirconia (8YSZ) for solid oxide fuel cells (SOFCs) was fabricated on anode substrates using reactive magnetron sputtering Zr-Y targets in a mixture Ar and O2 gases. The deposition 4−6 µm thin-film the transition or modes differing by oxygen concentration atmosphere. half-cell bending anode-supported SOFCs measured to determine residual stresses films after thermal annealing air. dependences were studied between modes, films, SOFC...
In this study, La0.6Sr0.4CoO3-δ (LSC) thin films were deposited by pulsed DC magnetron sputtering at oblique angle of the LSC target. The effect post-annealing temperature in range 600-1000°C on film crystalline structure was investigated. phase composition, and surface morphology determined using X-ray diffraction, scanning electron microscopy atomic force microscopy, respectively. Anode-supported solid oxide fuel cells (SOFCs) with bi-layered thin-film yttria-stabilized zirconia (YSZ) /...
The impact of a nanostructured NiO/yttria-stabilized zirconia (NiO/YSZ) and NiO/gadolinia-doped ceria (NiO/GDC) anode functional layers on low- intermediate-temperature solid oxide fuel cell (SOFC) performance is investigated. NiO/YSZ NiO/GDC thin films were reactively sputter-deposited by pulsed direct current magnetron sputtering from the Ni, Zr–Y, Ce–Gd targets onto commercial substrates. Anode-supported SOFCs based sputtered YSZ GDC electrolytes (∼4 µm) with without are fabricated. A...
