Characterization of YSZ Solid Oxide Fuel Cells Electrolyte Deposited by Atmospheric Plasma Spraying and Low Pressure Plasma Spraying

Microstructure and Electrical Conductivity of Atmospheric Plasma-Sprayed LSM/YSZ Composite Cathode Materials

“…The porosity of coating depends significantly on spray conditions. The previous studies into the lamellar bonded interface revealed that only a very limited lamellar is Owing to the lamellar structural feature with limited interface bonding, electrical conductivity is much less than that of identical bulk material, which has been confirmed by our previous study (Ref 14,18). Moreover, APS coating obviously presents anisotropy in electrical conductivity.…”

“…Moreover, APS coating obviously presents anisotropy in electrical conductivity. The previous ( Ref 14,18,24) studies revealed that the electrical conductivity of ceramic coating along the perpendicular direction to the coating surface was one-fifth to one-third of that of corresponding bulk materials. The electrical conductivity along the direction parallel to the surface is higher than that perpendicular to the surface.…”

The effect of solids and dispersant loadings on the suspension viscosities and deposition rates of suspension plasma sprayed YSZ coatings

“…Plasma spraying is a well established technique that allows ceramic coatings to be produced rapidly without the need for post deposition heat treatments, resulting in much recent interest in fabricating SOFCs using this technique [1][2][3]. Plasma spraying also facilitates use of ferritic stainless steel supports for SOFCs, which are inexpensive and have better mechanical, thermal and electrical properties than the cermet substrates currently used in state-of-the-art SOFCs.…”

Microwave sintering of plasma-sprayed yttria stabilized zirconia electrolyte coating

“…[5][6][7][8][9][10][11][12][13][14][15] It has been pointed out that, compared with APS YSZ coating, LPPS YSZ coating has a higher ionic conductivity and lower gas permeability. 8 However, the relatively low cost of APS makes this technique more competitive.…”
