“…The ability of the simple and cost-effective techniques in producing a comparable electrochemical performance of the LSC cathode at the intermediatetemperature with few reported studies in the literature (Table 2) is practically acceptable. Han et al [18] used a commercial inkjet printer as a cell fabrication technique and proved that a simple and cost-effective technique can produce a La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3-δ (LSCF) cathode with high electrochemical performance. Therefore, the simple G-S assisted with brush painting can still be regarded as a promising technique to fabricate LSC electrodes for intermediate-temperature PCFC application in a small-scale laboratory.…”

“…These approaches aided in optimizing the cathode structure on the electrolyte by reducing the deleterious effect upon transport of charge carrier species [15,16]. In the cell fabrication technique, most of the works reported on the effects of thickness, porosity, and sintering temperature on R p of the printed cathode layer or film [17][18][19]. Nevertheless, the studies on the effects of different slurries or ink preparations and slurry deposition techniques on the electrochemical properties of cathode materials are limited.…”

In this study, the effects of different fabrication techniques on the electrochemical performance of solgel derived La 0.6 Sr 0.4 CoO 3-δ (LSC) cathode material for intermediate temperature proton-conducting fuel cells were investigated. Single-phase, sub-micron LSC powder was used to prepare cathode slurries by a simple grinding-stirring (G-S) technique and an advanced ball milling-triple roll milling (BM-TRM) technique. The prepared G-S and BM-TRM cathode slurries were brush painted and screen printed, respectively, onto separate BaCe 0.54 Zr 0.36 Y 0.1 O 2.95 (BCZY) proton-conducting electrolytes to fabricate symmetrical cells of LSC|BCZY|LSC. The thickness of LSC cathode layer prepared by brush painting and screen printing was 17 ± 0.5 µm and 7 ± 0.5 µm, and the surface porosity of the layers was 32% and 27%, respectively. Electrochemical impedance spectroscopy analysis revealed that the layer deposited by screen printing had lower area specific resistance measured at 700°C (0.25 Ω cm 2) than the layer prepared by brush painting of G-S slurry (1.50 Ω cm 2). The enhanced LSC cathode performance of the cell fabricated using BM-TRM assisted with screen printing is attributed to the improved particle homogeneity and network in the prepared slurry and the enhanced particle connectivity in the screen printed film.

“…Research on inkjet printing of metal nanoparticles [ [9]] and carbonaceous materials [ [10]] have also been conducted. Such a rapid development is mainly due to its unique advantage of enabling a precise and selective deposition of materials into different architectures (thin films, 2D and 3D structures) with a very high resolution and minimal waste of materials [11][12][13][14]. The inkjet printing owns the further merits of being a low cost technique based on inks that can be easily formulated to be environmentally friendly.…”

“…7(b), the intermediate to low frequency range features the dominating process[42]. Moreover, the Bode plot peaks shift towards low frequencies with increasing temperature, which mainly corresponds to impedances related to diffusion or mass transport processes[43].Hence, LNO-30LDC oxygen electrode displayed encouraging performance in the SOFC mode. In order to evaluate the overall performance of the LNO-30LDC oxygen electrode in RSOCs operation, the hydrogen electrode supported single cell was measured at 700-800 o C under both in the SOFC mode and the SOEC mode.…”

In this work, La2NiO4+δ-xCe0.55La0.45O2-δ (denoted as LNO-xLDC) with various LDC contents (x = 0, 10, 20, 30 and 40, wt %) were prepared and evaluated as bifunctional oxygen electrodes for reversible solid oxide cells (RSOCs). Compared with the pure LNO, the optimum composition of LNO-30LDC exhibited the lowest polarization resistance (Rp) of 0.53 and 0.12 Ω·cm2 in air at 650 and 750 oC, respectively. The enhanced electrochemical performance of LNO-30LDC oxygen electrode was mainly attributed to the extended triple phase boundary and more oxygen ionic transfer channels. The hydrogen electrode supported single cell with LNO-30LDC oxygen electrode displayed peak power densities of 276, 401 and 521 mW·cm-2 at 700, 750 and 800 oC, respectively. Moreover, the electrolysis current density of the single cell demonstrated 526.39 mA·cm-2 under 1.5 V at 800 oC, and the corresponding hydrogen production rate was 220.03 ml·cm-2·h-1. The encouraging results indicated that LNO-30LDC was a promising bifunctional oxygen electrode material for RSOCs.
