“…In the case of YSZ, this resistance value can be reached at 700°C with a 15 µm highquality dense film deposited on a porous supporting anode or cathode [3]. Several approaches have been reported in the literature for the deposition of such films: electrochemical vapour deposition (EVD) [4], low pressure plasma spraying [5,6], RF sputtering [7], colloidal processes such as slurry-based dip or spray coating [8]. In this work electrophoretic deposition (EPD) was selected as a technique to obtain thin dense electrolyte films.…”

An original process for the preparation of YSZ dense films with a thickness lower than 10 µm over NiO-YSZ substrates is presented. This process involves the preparation of a green membrane of NiO-YSZ and subsequent electrophoretic deposition (EPD) of commercial YSZ powder on this polymer-rich membrane. A single thermal treatment allowed removal of the organic compounds, sintering of the layers and full densification of the electrolyte.

“…According to the volume of literature on the subject thermal spray and plasma spraying are both techniques more commonly seen in the literature to produce films for SOFC electrode/electrolyte materials as opposed to flame-based depositions (Ref [55][56][57][58]. Alternative, lower energy technologies have been explored that possibly promise alternative deposition techniques to plasma spraying.…”

The economic and technical breakthroughs in solid oxide fuel cell (SOFC) for commercial success still depend on high-quality manufacture, reliability, efficiency, and must have an acceptable cost when compared to competing technologies. The application of flame-based technologies as a one-step deposition technique for SOFC component manufacture has potential to reduce both cost and production time. In this article, cells produced by flame processes have been reviewed with emphases placed on the Reactive Spray Deposition Technology technique. Various experimental methods and examples for the synthesis of porous electrodes and dense electrolytes are reviewed. The studies focus on determining the range of the flame conditions under which each of the individual cell components for low temperature SOFC applications~600°C could be successfully deposited.

“…Since the late 1990s, an increasing number of works have been devoted to the realization of the whole solidoxide fuel cell by plasma spraying (Ref [1][2][3][4][5][6]. Indeed, the most important advantage of this technology versus conventional ones, such as screen printing, tape casting, etc, relies in the ability to manufacture the entire IT-SOFC with the same process.…”

Suspension Plasma Spraying of YPSZ Coatings: Suspension Atomization and Injection

2007

Among processes evaluated to produce some parts of or the whole solid-oxide fuel cell, Suspension Plasma Spraying (SPS) is of prime interest. Aqueous suspensions of yttria partially stabilized zirconia atomized into a spray by an internal-mixing co-axial twin-fluid atomizer were injected into a DC plasma jet. The dispersion and stability of the suspensions were enhanced by adjusting the amount of dispersant (ammonium salt of polyacrylic acid, PAA). A polyvinyl alcohol (PVA) was further added to the suspension to tailor its viscosity. The PVA also improved the dispersion and stability of the suspensions. The atomization of optimized formulations is described implementing Weber and Ohnesorge dimensionless numbers as well as gas-to-liquid mass ratio (ALR) value. Drop size distributions changed from monomodal distributions at low We to multimodal distributions when We number increases. The viscosity of the suspensions has a clear influence on the drop size distribution and suspension spray pattern. The secondary fragmentation of the drops due to the plasma jet was evidenced and the final size of the sheared drops was shown to depend on the characteristics of the suspension. Rather dense zirconia coatings have been prepared, which is a promising way to produce electrolyte.
