Fabrication of multilayers electrodes and electrolyte via screen printing for metal supported solid oxide fuel cell
Metal-Supported Solid Oxide Fuel Cell (MS-SOFC) were produced using a manual screen-printing method on 430 stainless steel (SS430) substrates. Each of MS-SOFC sample was fabricated by using manual screen printing with two different mesh screens which are 305 and 355. The fabrication of NiO-GDC...

description |
Metal-Supported Solid Oxide Fuel Cell (MS-SOFC) were produced using
a manual screen-printing method on 430 stainless steel (SS430) substrates. Each of
MS-SOFC sample was fabricated by using manual screen printing with two different
mesh screens which are 305 and 355. The fabrication of NiO-GDC composite anode
powder was done by mixing 60wt% NiO and 40wt% GDC. Meanwhile, 50wt% LSCF
and 50wt% GDC was mixed to produce LSCF-GDC composite cathode powder. NiO�GDC, LSCF-GDC and GDC powders went through calcination in the furnace at
950℃ for 2 hours. MS-SOFC samples with a different number of repetitions during
the screen-printing process were sintered at 900℃ for 90 minutes. In this study, the
phase analysis was conducted via X-Ray Diffraction (XRD) method for commercial
powder and composite powders. A good XRD pattern was obtained without the
presence of any secondary peak in composite anode and cathode powder. The XRD
data obtained were analysed to obtain the lattice structure and crystallise size for all
the commercial and composite powder. 24.59 nm, 24.38 nm, 13.34 nm are the average
crystallise size for NiO, GDC and LSCF, respectively. Scanning Electron Microscope
(SEM) and Energy Dispersive Spectroscopy (EDS) were used to identify the
thickness and distribution of elements on each MS-SOFC layer. As a result, the SOFC
component layers fabricated by screen printed using 305-mesh screen at 10 times
number of printings was selected as the ideal MS-SOFC sample. This is because the
thickness of the layers obtained is lower compared to layers from mesh screens 305
and 355 at 15 and 20 times the number of printings which is 11.8 μm, 11.9 μm and
18.2 μm for anode, electrolyte and cathode, respectively. Thin electrode layer will
produce low polarization resistance and can improve the SOFC performance itself. |
