“…However, the electrical conductivity of a stabilized zirconia electrolyte is three orders of magnitude lower than those of anode and cathode materials. The electrical 25) showed that the thickness of APS YSZ significantly influences the performances of SOFCs through ohmic polarization. Therefore, the effect of YSZ ohmic loss on the performance of SOFCs was examined using cermet-supported tubular SOFCs assembled with APS YSZ of different thicknesses and APS ScSZ.…”

“…SOFCs can reliably generate power because of relatively low internal electrolyte resistances even at low temperatures (500-400 °C) if a thin electrolyte fi lm can be fabricated. This can be achieved by using a number of deposition techniques, such as pulsed laser deposition (PLD), [8][9][10][11]17 ] plasma spraying, [ 19 ] electrostatic spray-assisted vapor deposition, [ 20 ] and physical vapor deposition. [ 21 ] However, internal resistances in cathodes still dominate the power generating properties of SOFCs at low temperatures (less than 500 °C).…”

“…A igualdad de potencia, la velocidad de una partícula proyectada con He es mayor que con H 2 [62]. El aumento de la intensidad de corriente eléctrica permite aumentar la potencia del plasma lo que implica un incremento de la cantidad de partículas correctamente fundidas [63].…”

“…Cuando la velocidad de inyección aumenta, reduciendo así la fuerza del arrastre, las partículas penetran más en el plasma. Mientras el argón no está ionizado su viscosidad aumenta con la temperatura [63]. La viscosidad del plasma puede ser aumentada también sustituyendo H 2 por He, y como resultado mejorando el arrastre de partículas y sus velocidades de esta forma los splats son más pequeñas y mejor aplastados [64].…”
