Surface modification of oxide capping layers on nickel catalyst for high performance hydrogen applications
This project aims to develop and study the SDC interlayer thickness for the fabrication of Nickel and Yttria-Stabilised Zirconia (Ni-YSZ) anode onto a Lanthanum Strontium Gallium Magnesium (LSGM) electrolyte base. The purpose is to prevent the formation of La2Zr2O7 and LaNiO3 phases due to Ni-...

| description | This project aims to develop and study the SDC interlayer thickness for the fabrication
of Nickel and Yttria-Stabilised Zirconia (Ni-YSZ) anode onto a Lanthanum Strontium
Gallium Magnesium (LSGM) electrolyte base. The purpose is to prevent the formation
of La2Zr2O7 and LaNiO3 phases due to Ni-YSZ and LSGM reacting during sintering.
LSGM pellets were formed using a mechanical press with purchased powder. SDC of
varying thickness were deposited onto the LSGM pellets using sputtering method. Ni
YSZ was screen-printed onto the SDC coating of the LSGM, thus creating
LSGM/SDC/Ni-YSZ half cells. The cells were subjected to EIS readings at 600°C,
700°C and 800°C to simulate intermediate operating temperatures. From EIS readings,
it was determined that an SDC thickness of 200nm (SDC 200nm) had the lowest
polarisation resistance (Rp). SDC thickness lesser than 200nm had an Rp lower than
the reference sample without SDC (Bare LSGM). SDC thickness above 200nm
showed to be detrimental to the overall performance of the SOFC. Finally, a 10-hour
degradation test was carried out at 800°C between SDC 200nm and Bare LSGM, with
SDC 200nm having better results throughout the simulated operation. |
