“…Although these studies show that electrolytes and other components can be manufactured by inkjet printing, only a few studies report SOFCs with functional electrolytes with thicknesses of about 1 mm. Early promising results were obtained by Sukeshini and Cummins, who printed a YSZ electrolyte of about 10 mm by multiple printing (up to 12 layer-over-layer depositions) in a fully inkjet-printed SOFC [12]. In this and in other cases, multiple printings were necessary to seal the electrolyte to achieve acceptable performance and leak tightness of the cells.…”

Drop-on-demand inkjet printing -a mask-less, fine write, and high throughput technique -is attractive for fabricating miniature ceramic devices. In this study, high quality, fine-featured solid oxide fuel cell (SOFC) cathode micropatterns were demonstrated using inkjet printing. The influence of the droplet kinematic properties on final drop deposition was studied by adjusting ink temperature and droplet velocity to obtain a wide range of Weber and Z values, i.e. 0 < Weber < 57 and 0 < Z < 24. Terpineol-based inks were evaluated, with or without dispersant (polymeric ethyl cellulose) and/or active cathode material (La 0.6 Sr 0.4 Fe 0 . 8 Co 0.2 O 3 ). The balance of inertia to the surface energy of the jetted droplet was found to play a prominent role in the stability of droplets. The Weber number was found to be the good predictor for stable jetting. At Weber > 35 printing defects from splashes and satellites were present. At Weber < 35 the droplets coalesced into uniform, round circles without splashes or satellite defects. Defect-free printing was essential toward achieving uniform micropatterens such as micro dot arrays or micro lines which are on the scale of 100 microns or less.

“…For instance, excessive Ni and Fe diffusion into the solid electrolyte can induce its electronic conductivity. In this work, we have optimized the inks and achieved a balanced composition of the supports, with the suitable amounts of additives, enabling to lower the temperature of electrolyte sintering to 1350°C, in comparison to the previously reported 1450°C for the systems with similar architecture (9).…”

The bimetallic nickel-iron anode-supported SOFCs were fabricated, with their microstructure analysed, and the performance evaluated at the intermediate temperatures. The produced anode supports were made with the base composition of NiO:Fe 2 O 3 (7:3)mol% and addition of sintering aids. The discs-shaped substrates were die-pressed, with the active layers deposited using Direct Ceramic Inkjet Printing (DCIJP) of suspension inks. The 10µm thicknesses were achieved for the printed electrolyte layer. The DCIJP has also enabled infiltrating the scaffolds of porous supports, thus extending the active area of electrode. The electrolyte material was comprised of 10Sc1CeSZ, whereas cathode was LSCF/CGO composite. Samples with fully co-sintered active layers were produced, alongside the optimised amount of additives, and the adjusted coefficients of thermal expansions. The cell was tested in 4%H 2 in Ar gas and dry air, and has displayed open circuit potential of ~0.8V at 750°C.
