Key Points

The aim is to enhance carbon tolerance in Ni/GDC thin-film anodes for more efficient SOFC operation using syngas.
Utilized bottom-up redox state engineering to modify anode properties.
Characterized the performance of the anodes under syngas conditions.
Evaluated carbon deposition effects on electricity generation efficiency.
Improved carbon tolerance was observed with engineered anodes, leading to a 20% increase in electricity output.
Reduced carbon deposition was quantified, with a 30% reduction compared to unmodified anodes.
The optimized thin-film anodes showed significant longevity, maintaining performance over extended tests.

Implication

Demonstrates carbon tolerance enhancement in syngas-fueled SOFCs, implying improved efficiency.

Abstract

Syngas-fueled solid oxide fuel cells (SOFCs) offer an efficient route for converting carbon-rich feedstock into electricity. However, it introduces critical challenges, such as carbon deposition on the anode, which significantly...
