In this work the fabrication of a BaCe0.85Y0.15O2.925 (BCY) dense and thin layer by wet powder spraying (WPS) was investigated, with the aim to produce an anode-supported protonic cell using relatively simple and low cost processes. The spraying deposition was performed on Ni-BCY anode supports. In order to better match the shrinkage of...

Half-cells consisting of YSZ electrolyte pellets and slurry-coated cathodes were tested with a three-electrode configuration. The composite cathodes considered in this study had a fixed LSM/YSZ volume ratio equal to 1 and variable apparent surface areas, ranging from 0.05 to 0.25 cm2. Electrochemical Impedance Spectroscopy and potentiodynamic...

This paper describes the first part of an exper- imental and theoretical study performed on composite Lanthanum Strontium Manganite (LSM) and Yttria-stabi- lized Zirconia (YSZ) electrodes. Cathode electrocatalytic activity was investigated using different cell configurations and carrying out potentiodynamic polarisation and elec- trochemical...

The catalytic activity of Ni-based anodic materials was investigated in complete solid oxide fuel cells (SOFCs) by electrochemical analysis. Button cells, consisting of supporting yttria-stabilized zirconia (YSZ) electrolyte layer, (La1-xSrx)y MnO3 (LSM) cathode and (cermet) Ni0.5Co0.5–YSZ anode were employed. Powders for anodes were obtained...

A comparative impedance study of pure ff{ G,a-r=,Sr".)rMnO3_5 rvith x : 0.25 and y :0.95) and composite LSM/YSZ {Zroz-8 mol.Yo YzO:) cathode materials for SOFC is performed. The technique of ihe Differential Impeiance Analysis (DIA), which ensures structural identihcation without any preliminary hypothesis, is applied to the data analysis. It...

Solid oxide fuel cells (SOFC) are a forward-looking technology for highly efficient, environmentally–friendly power generation. SOFC single cells and stack systems are multilayer structures consisting of ceramic and metallic materials with different well defined electrical transport properties. All components have to show well-adjusted thermal...

A procedure for evaluation and elimination of errors, caused by parasitic inductance and resistance in EIS studies of two solid oxide fuel cells (SOFC) materials: yttria stabilized zirconia (YSZ) electrolyte and lanthanum strontium manganite (LSM)/YSZ composite cathode is presented in this paper. It is shown that for these low impedance systems...

This paper deals with the fabrication and electrochemical study of a high temperature solid electrolyte supporting cell operating as SOFC (Solid Oxide Fuel Cell) and SOEC (Solid Oxide Electrolysis Cell). The cell is based on a dual membrane (DM) electrolyte design, advantageously separating the cell into three different chambers: hydrogen side,...
