| description | <p>A new setup for characterization of solid material oxygen exchange and
conductivity in a broad oxygen partial pressure range and at elevated
temperatures is presented. The development target of this setup is directed
towards the detection of ultra-low amounts of exchanged oxygen. For this,
electrochemical cells made of yttria-stabilized zirconia (YSZ) were optimized
and applied in a flow-through arrangement. The design and process measures
enable a lower limit of detection below 100 pmol of exchanged oxygen.
Furthermore, the system characteristics concerning oxygen dispersion,
titration efficiency and electrode kinetics are described.</p> |
