Resumo
A hydrothermal route was used to synthesize gadolinia-doped ceria
with highly dispersed Ni particles. The microstructural and
electrical properties of the cermet revealed that Ni attained
percolation at relatively low volume fraction. The cermet was used
as a catalytic layer deposited onto the standard Ni-based anode and
allowed for the stable operation under ethanol. No evidence of
carbon deposits was identified after 50 hours of continuous
operation under dry ethanol. Such a result was attributed to both
the catalytic properties of the ceria layer and the operation
mechanism of gradual internal reforming.
