Short summary
For the understanding of new materials, especially oxides, oxygen exchange of such materials and its consequences for their properties are of high interest. For this purpose a new setup for oxygen solid electrolyte coulometry with electrochemical cells made of yttria-stabilized zirconia (YSZ) is presented. It could be shown that this setup enables the measurement of exchanged oxygen from the picomol up to the higher nanomol range with a precision which was not achieved so far.
