Abstract

In a coupled system of O concn. cells with yttria-stabilized zirconia (YSZ) as electrolyte, the behavior vs. time of their emf. is given when the common atm. is initially made up of Ar with an O partial pressure of 1 × 10-14 Pa at 1118 K.  A break-point characterizes all the curves, but it occurs at different times, depending on the exptl. setup, but at the same emf. value.  Adsorption of O on a porous Pt electrode is assumed to occur, and the free energy change of desorption was 234 kJ/mol.
