Two different low Ni content (10 wt.%) anode catalysts were investigated for intermediate temperature (800 β’ C) operation in solid oxide fuel cells fed with dry propane. Both catalysts were prepared by the impregnation of a Ni-precursor on different oxide supports, i.e. gadolinia doped ceria (CGO) a

Using electrochemical impedance spectroscopy, the high frequency (HF) and low frequency (LF) impedance of nickel-gadolinium-doped ceria (Ni-CGO) symmetrical cells (Ni-CGO/YSZ/Ni-CGO) in dry and moist atmospheres were studied. The HF component of the impedance response in moist H 2 varied with operat
