“…For the preliminary tests of LaNi0.5Cu0.5O3-δ as the air electrode for the fuel electrode supported cells with 8YSZ electrolyte half cells (5 cm x 5 cm) with the following configuration: Ni-8YSZ/8YSZ/CGO were used. The cells were prepared with standard procedures developed at the Institute of Power Engineering, which details can be found in (25,26). Air electrode paste based on the LaNi0.5Cu0.5O3-δ and terpineol with other additives (binder and plasticizer) was manually screen-printed on the half cells (air electrode area 16 cm 2 ), which were in the next step annealed at 800 °C for 2 hours in the air (sintering condition analogous to the presented in the ref.…”

In this work, the assessment of LaNi0.5Cu0.5O3-δ-based perovskite in terms of the availability of critical raw materials, sustainability, and economic aspect in relation to the Co-based oxides is presented. Chemical compatibility between LaNi0.5Cu0.5O3-δ, obtained by the sol-gel method, and commercial CGO powder is evaluated. Moreover, the electrochemical studies of fuel electrode-supported cells with LaNi0.5Cu0.5O3-δ material as the air electrodes are presented. The electrochemical measurements - current density-voltage curves, were measured at different conditions including temperature in the 700-800 °C range and variation of the composition of feeding gases.

“…by reducing the thickness of the electrolyte layer and/or resistivity of the electrolyte material. Screen-printing is a cost-effective method that has been able to produce electrolyte layers with thicknesses around 2.5 -20 μm [44][45][46][47][48]. Lee et al reported of a SOFC based on 5 μm thick GDC electrolyte layer prepared by dip-coating that achieved a power density of 1970 mW/cm 2 at 550 °C [49].…”

“…The lowering of the working temperature of Solid Oxide Fuel Cells (SOFC) down to the intermediate temperature (IT) range is, at present, crucial for the widespread use of this energy technology. The use of Doped Ceria (DC) barrier layers between the cathode and the electrolyte can improve the SOFC’ efficiency even if the working temperature lowers to the IT range (500 °C–700 °C) [ 1 , 2 , 3 , 4 ]. This temperature lowering is beneficial from the point of view of material durability and, consequently, in terms of the durability of the SOFC performance.…”

We investigate the influence of position, under large circular sputtering targets, on the final electrochemical performance of 35 mm diameter button solid oxide fuel cells with sputter-deposited Gadolinium doped Ceria barrier layers, positioned in order to almost cover the entirety of the area associated with a 120 × 80 mm2 industrial cell. We compare the results obtained via structural and morphological analysis to the Electrochemical Impedance Spectroscopy (EIS) measurements performed on the button cells, disentangling the role of different parameters. The Atomic Force Microscopy analysis makes it possible to observe a decrease in the roughness values from the peripheral to the central zones under the sputtering target, with peak-to-valley roughness values, respectively, decreasing from 380 nm to 300 nm, while Scanning Electron Microscopy and Energy Dispersive Spectroscopy show a dependence of the layer coverage from the position. The electrochemical performances of button cells with buffer layers of only 200 nm in thickness, and with negligible thickness gradients across them, show current density values of up to 478 mA/cm2 at 0.8 V and 650 °C, with an improvement of more than 67% with respect to button cells with standard (screen printed) buffer layers. These results point out the major influence exerted by parameters such as the thickness gradient and the coverage of the sputtered buffer layers in determining the final electrochemical performances.
