“…However, spin coating has gained attention as a method to produce thin layers for SOFCs, which can be used for layer depositions for both electrolyte-and anode-supported cells [10][11][12][13][14][15][16][17][18][19]. Such technique is based on the deposition by rotation in which a suspension is spread across the surface of a substrate by a centrifugal acceleration.…”

“…Such technique is based on the deposition by rotation in which a suspension is spread across the surface of a substrate by a centrifugal acceleration. It is a widely used technique in the electronic industry, in microlithography for the manufacture of integrated circuits and for fabrication of antireflective coatings in solar cells [10][11][12][13][14][15][16][17][18][19]. Spin coating has been successfully developed to fabricate both porous electrode layers and dense electrolyte films for anode supported SOFCs, evidencing the suitability of such deposition technique [10][11][12][13][14][15][16][17][18][19].…”

Electrodes for electrolyte-supported solid oxide fuel cells (SOFC's) were fabricated by spin coating. Strontium-doped lanthanum manganite (LSM) cathode and nickel yttria-stabilized zirconia cermet anodes were synthesized and processed for enhanced deposition conditions. The influence of electrode microstructural parameters was investigated by a systematic experimental procedure aiming at optimized electrochemical performance of single cells. Polarization curves showed a strong dependence on both electrode thickness and sintering temperature. By a systematic control of such parameters, the performance of single cells was significantly enhanced due to decreasing of polarization resistance from 26 Ω cm² to 0.6 Ω cm² at 800°C. The results showed that spin-coated electrodes can be optimized for fast and cost effective fabrication of SOFCs.

Ni0.75Fe0.25Ox-GDC cermet anode for intermediate temperature solid oxide fuel cell was prepared by hard template method and wet impregnation method. LSC-GDC cathode-supported single cell was fabricated by using Ni0.75Fe0.25 coated tubular GDC as anode for the performance test. The composite anode material with Ni-Fe alloy particles coated tubular GDC was analyzed by XRD and SEM. The maximum power density of the single cell in hydrogen and dry methane was 736 and 400 mW·cm-2 at 800 °C, respectively. The SEM observation showed that the anode had a porous three-dimensional microstructure with high specific surface and rich gas channel, resulting a high power generation performance.

“…Mn-Co-Y-O spinel coatings [10] were prepared on AISI 430 and Crofer 22 APU steels by the magnetron sputtering. A combined Ce/Co alloy coatings [11] were deposited on metallic interconnects by physical vapor deposition process, and Co/CeO 2 composite coatings [12] were electroplated on the ferritic stainless steels Crofer 22 APU and Crofer 22 H. Lanthanum (La) is usually synthesized as perovskite cathode and interconnect material for intermediate temperature solid oxide fuel cell [13][14][15][16]. High temperature oxidation characteristics of active element Lanthanum have been investigated in alloys.…”

Abstract:To prevent Cr poisoning of the cathode and to retain high conductivity during solid oxide fuel cell (SOFC) operation, Cu or La doped Co-Mn coatings on a metallic interconnect is deposited and followed by oxidation at 750 • C. Microstructure and composition of coatings after preparation and oxidation is analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). High energy micro arc alloying process, a low cost technique, is used to prepare Cu or La doped Co-Mn coatings with the metallurgical bond. When coatings oxidized at 750 • C in air for 20 h and 100 h, Co 3 O 4 is the main oxide on the surface of Co-38Mn-2La and Co-40Mn coatings, and (Co,Mn) 3 O 4 spinel continues to grow with extended oxidation time. The outmost scales of Co-33Mn-17Cu are mainly composed of cubic MnCo 2 O 4 spinel with Mn 2 O 3 after oxidation for 20 h and 100 h. The average thickness of oxide coatings is about 60-70 µm after oxidation for 100 h, except that Co-40Mn oxide coatings are a little thicker. Area-specific resistance of Cu/La doped Co-Mn coatings are lower than that of Co-40Mn coating. (Mn,Co) 3 O 4 /MnCo 2 O 4 spinel layer is efficient at blocking the outward diffusion of chromium and iron.
