Resumen:
Pt nanoparticles, in a size range which varies from 3 to 20 nm, were dispersed in the porosity of a 7.5 µm-thick layer of LSCF-GDC electrode interfaced on a dense GDC membrane. Small positive polarizations (200 µA / 0.8V - 1.2V) can strongly increase the Pt nanoparticles catalytic performance for propane deep oxidation at low temperatures (267°C-338°C). 40%-enhancement of the propane conversion was achieved with apparent Faraday efficiency values up to 85. These results clearly demonstrate that metallic nanoparticles dispersed in the porosity of a mixed ionic electronic conducting electrode can be electropromoted.
