- Abstract
- A carbon-supported Palladium electrocatalyst was investigated for oxygen reduction and
hydrogen oxidation in a polymer electrolyte fuel cell operating at intermediate temperatures
(80e110 ?C) and with low relative humidity (33%). A 30% Pd/C was synthesized by a
colloidal method and subsequent carbothermal reduction. A mean particle size of 4.0 nm
and a homogeneous dispersion of Pd particles on the support were obtained. The performance
of the Pd catalyst was compared to those obtained with a 50% Pt/C catalyst and a
50% Pt3Co1/C as anode and cathode, respectively. The Pd/C catalyst showed low overpotential
for hydrogen oxidation whereas its performance as cathode was significantly
lower than the benchmark Pt3Co1 catalyst. The main limiting effects for the Pd-based
electrocatalyst appeared to be associated to a larger mean particle size compared to the
benchmark Pt catalysts and to the modification of the carbon support during the synthesis
procedure. These effects led to a stronger activation control, a slight increase of the series
resistance and some diffusion constraints. (literal)
