“…Regarding the electrolyte, several of these studies have been devoted to the fabrication of dense yttria-stabilized zirconia (YSZ) layers with a thickness below 10 μm onto different porous and dense substrates. Li et al [17], Tomov et al [18], and Sukeshini et al [19] deposited fully functional YSZ electrolytes by inkjet printing directly on tape cast and pre-sintered NiO-YSZ cermet substrates typically used in anode-supported SOFCs. Full SOFCs based on these inkjet-printed dense electrolytes were fabricated in all cases showing excellent open circuit voltages (OCVs), OCV = 1.1, 1.01 and 1.05 V, respectively, operating under hydrogen at 800ºC.…”

“…As part of previous work related to the development of Solid Oxide Fuel Cells [1][2][3][4][5][6][7][8][9] at IEn OC CEREL, research and development of half-scale manufacturing technology of flat, thin Anode Supported Solid Oxide Fuel Cell (AS-SOFC) with dimensions of 50 x 50 mm and 100 x 100 mm was conducted. In this technology, anode supports are produced by means of highly reproducible, novel method of high-pressure injection molding and the other functional layers are made by screen printing method [7,9].…”

Abstract. Fuel cells are devices converting the chemical energy into the electrical energy and heat as result of the electrochemical reaction between gaseous fuel and a gas oxidant in flameless combustion process. Because of omission of thermo-mechanical steps that are present in any traditional energy conversion technology (e.g. gas turbine) fuel cells show increased efficiency in comparison. Compact sizes and modular scalability predestines this technology for distributed energy generation including but not limited to renewable energy sources (e.g. wind, solar). Fuel cells technology also addresses other very important part of distributed renewable energy generation. Because of the unreliable energy production rates and the usual for renewable energy sources mismatch between energy supply and demand, some sort of energy storage is needed to store surplus of produced energy and release it when needed. Reversible fuel cells, that generate hydrogen from available surplus of energy and then generate energy from that stored fuel when needed are cheaper and more ecologically friendly alternative to usually used batteries. This technology is still under development, including research at IEn OC CEREL. In the early development of reversible fuel cells, new types of nickel oxide and porosity forming carbon was evaluated for this task. This work compares the electrical and mechanical parameters of SOFC manufactured with JT Backer NiO and Carbon Polska carbon with cells made from other commercially available materials. Based on evaluated quality, purity, availability and cost, following materials were selected for comparison: Novamet NiO, 99,9 % pure, grain size 1-2 µm and Aldrich carbon with parameters similar to graphite used previously. Preliminary tests show clear changes in the microstructural, mechanical and electrical parameters.

“…The technology is cost effective and environmentally friendly through waste minimization of the expensive precursors, which is a critical issue especially for inks based on precious or rare-earth metals. The production of anodes and electrolyte coatings with modified ''Domino MacroJet'' print head was reported previously by Tomov et al [30] and Wang et al [31] using suspension inks. Wang et al [32] successfully deposited thin GDC electrolytes on NiO-8YSZ cermet anodes using sol-gel-based precursor solutions.…”

“…These activation energy values were typical for the Ni-CGO/CGO/Ni-CGO symmetrical cell reported in the literature-E a = 140 kJ mol -1 was reported by Almar et al [38] for mesoporous Ni-CGO anodes; Muecke et al [39] found that thin film Ni-GDC anodes exhibited E a = 145 kJ mol -1 ; Galinski et al [40] reported E a = 164 kJ mol -1 for sprayed Ni-40GDC anodes. The relatively high summit frequencies, the similarity of the activation energies over the measured temperature range and the linearity of ASR inf versus N dependence suggested that a charge transfer process was the most likely rate limiting step among the reactions occurring in the infiltrated anode [16,23,30]. Hence, the impregnation of mixed ionic and electronic conductive oxide (GDC) into a composite NiO-GDC scaffold led to the extension of TPB by percolating GDC nano-decoration.…”

The effect of inkjet printing infiltration of Gd 0.1 Ce 0.9 O 2-x in NiO-Gd 0.1 Ce 0.9 O 2-x anodes on the performance of symmetrical and button cells was investigated. The anodes were fabricated by inkjet printing of suspension and sol inks. Symmetrical cells were produced from composite suspension inks on Gd 0.1 Ce 0.9 O 2-x electrolyte. As-prepared scaffolds were infiltrated with Gd 0.1-Ce 0.9 O 2 ink. Increasing the number of infiltration steps led to formation of ''nano-decoration'' on pre-sintered anodes. High resolution SEM analysis was employed for microstructural characterization revealing formation of fine anode sub-structure with nanoparticle size varying in the range of 50-200 nm. EIS tests were conducted on symmetrical cells in 4% hydrogen/argon gas flow. The measurements showed substantial reduction of the activation polarization as a function of the number of infiltrations. The effect was assigned to the extension of the triple phase boundary. The i-V testing of a reference (NiO-8 mol% Y 2 O 3 stabilized ZrO 2 /NiO-Gd 0.1 Ce 0.9 O 2-x /Gd 0.1 Ce 0.9-O 2-x /Gd 0.1 Ce 0.9 O 2-x -La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3-d ) cell and an identical cell with infiltrated anode revealed *2.5 times improvement in the maximum output power at 600°C which corresponded with the reduction of the polarization resistance of the symmetrical cells at the same temperature (2.8 times). This study demonstrated the potential of inkjet printing technology as an infiltration tool for cost effective commercial SOFC processing. Graphical abstract
