“…Gas permeation can occur by means of viscous flow, Knudsen flow and/or surface diffusion in the porous medium, which will be discussed in the following part. However, in the literature [12,15,16], viscous flow was often adopted to process the obtained gas permeation data for plasmasprayed ceramic coating.…”

“…Under the test conditions (900°C) a current density of 200 mA/cm 2 was obtained, this meant 40 W per tube with 22 cells. Within this program also a pressurized ($5 bar) 10 kW class module comprising 414 of such tubes was successfully operated ( Ref 9,95). This approach was continued for some years with wet powder/sintering technology replacing plasma spraying.…”

Fuel cells directly convert chemical energy into electrical energy with the potential of very high-efficiency values, because they are not subjected to the Carnot relationship. Of the different fuel cell types in particular Solid Oxide Fuel Cells (SOFC) meet a high interest for different applications due to their specific advantageous properties. They operate in the high temperature range around and above 800°C and consist in the electrochemical active part mainly of ceramic material. Their economic and technical breakthrough depends still on the success to realize them with high quality, reliability, and efficiency and in particular with acceptable and attractive costs. Different manufacturing methods are in application or under development for the production of the cell components. Beneath these methods are also plasma spray technologies. This review will show the specific demands, the performed and ongoing work, the state of development and especially the required R + D goals to render this type of methods successful.

“…Low pressure plasma spraying (LPPS) and atmospheric plasma spraying (APS) are employed to deposit YSZ electrolyte coatings. [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.…”
