abstract = {Anode-supported solid oxide fuel cells accumulating more
than 700 h of stable operation on dry ethanol with high
current output are reported. A highly active ceria-based
catalytic layer deposited onto the anode efficiently
converts the primary fuel into hydrogen using the
electrochemically generated steam. On the other hand,
standard fuel cells without the catalytic layer collapse
because of carbon deposit formation within the initial 5 h
of operation with ethanol. The nanostructured ceria-based
catalyst forms a continuous porous layer (∼25 µm thick)
over the Ni-based anode support that has no apparent
influence on the fuel cell operation and prevents carbon
deposit formation. Moreover, the catalytic layer promotes
overall steam reforming reactions of ethanol that result in
similar current outputs in both hydrogen and ethanol fuels.
The stability of single cells, with relatively large active
area (8 cm2), confirms the feasibility of a catalytic layer
for internal reforming of biofuels in solid oxide fuel
cells. The experimental results provide a significant step
towards the practical application of direct ethanol solid
oxide fuel cells.},
