Effect of electrolyte thickness manipulation on enhancing carbon deposition resistance of methane-fueled solid oxide fuel cell
Dual-layer hollow fiber (DLHF) micro-tubular solid oxide fuel cell (MT-SOFC) consisting of nickel oxide-yttria-stabilized zirconia (NiO-YSZ) anode/YSZ elec�trolyte was fabricated via a single-step phase inversion-based co-extrusion/co�sintering technique in order to investigate the effect of differ...

| description | Dual-layer hollow fiber (DLHF) micro-tubular solid oxide fuel cell (MT-SOFC)
consisting of nickel oxide-yttria-stabilized zirconia (NiO-YSZ) anode/YSZ elec�trolyte was fabricated via a single-step phase inversion-based co-extrusion/co�sintering technique in order to investigate the effect of different electrolyte
extrusion rates (1-5 mL min−1
) at different sintering temperature (1350�C,
1400�C, and 1450�C) under methane (CH4) condition. The DLHF co-sintered
at 1450�C was chosen as optimum temperature due to the good mechanical
strength and gas-tight property. Meanwhile, 18 to 34 μm of electrolyte thick�ness was achieved when electrolyte extrusion rate increase from 1 to
5 mL min−1
. Power density as high as 0.32 W cm−2 was obtained on the cell
with the electrolyte layer of 18 μm in thickness (DLHF1) which is 20% higher
than the cell with an electrolyte layer of 34 μm (DLHF5) which was only
0.12 W cm−2 when operated at 850�C. However, DLHF1 had suffered cracking
formation that originated from anode site which shortened the stability test
duration to only 8 hours of survival under 750�C. While DLHF5 can operate
up to 15 hours but an increase in electrolyte thickness had resulted in higher
ohmic area-specific resistance that lowering the power density. Fifty-seven per�cent reduction in cell performance was observed under methane condition
when compared to the cell that performs using hydrogen gas due to the carbon
deposition as proven by Raman spectroscopy and carbon, hydrogen, nitrogen,
and sulfur analyzer. |
