| Popis: | In order to increase efficiency of metal-supported solid oxide fuel cells (SOFCs) and electrolysis cells (SOECs) and to lower their fabrication and operation temperatures, development of novel methods for the functional layers deposition is of primary importance. In this work, the composite anodes of metal-supported solid oxide cells (MS-SOCs), made of Ni and 10 mol.% scandia and 1 mol.% yttria co-stabilized zirconia (10Sc1YSZ), were deposited by the aerosol deposition (AD) onto high relief porous metal substrates. This step was followed by magnetron sputtering (MSP) of thin 8 mol.% yttria-stabilized zirconia (8YSZ) solid electrolyte. Vacuum co-sintering of the half-cells at 1100 °C resulted in the formation of well-bonded nanostructured anodes and gas-tight electrolyte membranes. The area-specific ohmic resistance of the half-cell in dry hydrogen was 0.23 Ohm·cm2 at 577 °C. |
