Abstract
The mechanisms widely suggested for the O2-reduc-tion or
H2-oxidation SOFC reactions involve inter-mediate O/H species
adsorbed on the electrode surface. The presence of these
intermediates is investigated by linear sweep voltammetry. In
airat moderate temperatures (500øC) Pt in contact with YSZ is
covered with adsorbed oxygen which vanishes at high temperature
(1000øC). On Ni (YSZ) a specific layer of NiO is observed abovethe
equilibrium potential while no surface species can identified at
SOFC anode conditions.
