abstract = {In the gradual internal reforming (GIR) process, the water
released by the electrochemical oxidation of hydrogen at the
anode is used for the steam reforming of the fuel in the
catalytic layer deposited over the anode of the SOFC. We
have developed a highly active ceria-based catalytic layer
that efficiently converts the primary fuel (ethanol or
methane) into hydrogen using the electrochemically-generated
steam. Ir/CGO catalyst was pretreated at 1173 K in He flow
with less than 0.5 ppm O2 prior to catalytic testing. The
catalyst consists of Ir nanoparticles (mean size of 4 nm in
diameter) supported on the surface of sub-micron
gadolinia-doped ceria particles and forms a continuous
porous layer (~25 μm thick) over the Ni-based anode. An
anode-supported solid oxide fuel cell (SOFC) was
continuously operated for more than 300 hours with direct
methane or (anhydrous) ethanol, with a high current density.
The catalytic layer associated with the GIR process avoids
the carbon deposition on the anode material surface. Such
results represent a significant advance towards the
development of fuel-flexible SOFC operating with methane or
ethanol.},
