## Abstract

The effect of pressure on the emf of solid-state galvanic cells: $Pt|Ni + NiO|ZrO_2(CaO)|Cu + Cu_2O|Pt (cell I) and Pt|SFeO + Fe_3O_4|ZrO_2(CaO)||Fe_3O_4 + Fe_2O_3|Pt$ (cell II) were measured in the pressure range 1.01 \times 105 to 8.08 \times 108 Pa. Within experimental error, the emf was found to vary linearly with pressure: EI (1000 K)/mV = 275.5 + 2.62 | 10-8 [(P/Pa) - 101,325] EII (896 K)/mV = 442.5 - 2.45 10-8 [(P/Pa) - 101,325]. These results are consistent with available data on entropy and volume changes associated with the cell reactions.
