abstract = {The present study focuses on structural and dynamical
properties of the catalytic layer for high-temperature
polymer electrolyte fuel cells (HT-PEFC). The catalytic
layer is a composite material containing nanoporous carbon,
poly(tetrafluoroethylene) (PTFE) and platinum (Pt)
nanoparticles. The structure of the catalyst is investigated
using small angle X-ray scattering (SAXS) following
different preparation steps of the electrodes: pure carbon
support, platinum/carbon (Pt/C) powder and finally, complete
catalytic layer. The structural properties of the Pt/C
powder containing different amounts of Pt are discussed
along with the size distribution of Pt particles and their
arrangement on the surface of the carbon support. Following
the preparation sequence of the catalytic layer based on the
Pt/C powders the electrodes with different final Pt loadings
are analyzed in details. Investigation of the structure of
the catalytic layer is accompanied by the study of
nanosecond dynamics of the phosphoric acid (PA) in the
catalytic layer containing different amount of Pt by means
of neutron backscattering spectroscopy. The structure of the
catalytic layer is mostly determined by the structure of the
catalytic powder and does not vary significantly with Pt
loading in the electrode. The behavior of the PA is
sensitive to the Pt content in the electrode.},
