“…Solid oxide cells (SOC) offer several advantages over proton exchange or alkaline cells due to their operation at high temperatures, typically above 750 • C presenting faster reaction kinetics and thermodynamic advantages, resulting in higher power densities and improved overall performance and efficiency. With an impressive energy conversion efficiency of up to 80%, SOC technologies demonstrate their potential as highly efficient energy storage and conversion systems [15].…”

Solid oxide cells are an efficient and cost-effective energy conversion technology able to operate reversibly in fuel cell and electrolysis mode. Electrolyte-supported solid oxide cells have been recently fabricated employing 3D printing to generate unique geometries with never-explored capabilities. However, the use of the state-of-the-art electrolyte based on yttria-stabilized zirconia limits the current performance of such printed devices due to a limited oxide-ion conductivity. In the last years, alternative electrolytes such as scandia-stabilized zirconia became more popular to increase the performance of electrolyte-supported cells. In this work, stereolithography 3D printing of scandia-stabilized zirconia co-doped with ytterbia was developed to fabricate solid oxide cells with planar and corrugated architectures. Symmetrical and full cells with about 250 μm-thick electrolytes were fabricated and electrochemically characterized using impedance spectroscopy and galvanostatic studies. Maximum power density of 500mW/cm2 in fuel cell mode and an injected current of 1A/cm2 at 1.3V in electrolysis mode, both measured at 900ºC, were obtained demonstrating the feasibility of 3D printing for the fabrication of high-performance electrolyte-supported solid oxide cells. This, together with excellent stability proved for more than 350h of operation, opens a new scenario for using complex-shaped solid oxide cells in real applications.

“…Electric cars can also be powered with fuel cells. The technology of fuel cells is intensively developed at the Warsaw University of Technology [10][11][12][13]. It is likely that a large number of electric cars can increase the differences between the peaks and valleys of demand for electricity, which is why it is worth considering the methods of energy storage [14][15][16][17].…”

The following paper focuses on the electric vehicles sector development and its possible influence on power system load in Poland. The goal is to estimate the increase of power demand resulting from the electric cars charging. First of all, the current legal environment, which provides a framework for the e-mobility sector evolution, was described. Furthermore, the technical process of electric vehicles charging was depicted and the applicable methods of cooperation between e-mobility and power system were proposed. The quantitative analysis of the impact of the electric vehicles charging on the power demand in the National Power System was conducted. The input data and adopted assumption were specified. The structure of the calculation model and the differences between analyzed scenarios were described. The outcome obtained for the National Power System and Warsaw distribution area were presented.
