Abstract
Abstract: Solid Electrolyte Potentiometry is an electrochemical method to characterise the state of solid catalysts under working conditions. Its application is temperature limited due to polarization effects at the catalyst electrode. A new operational definition of this temperature limit is proposed which is based on the measurements of exchange current densities.
